Inthis collection of videos, Trevor Hastie and Rob Tibshirani interview authors of seminal papers in the field of statistics. This project was part of Stanford's STATS 319 class held in Winter Quarter of 2024.

Our IA Program develops practical relationships between the department and the industrial community by creating opportunities for scientists, engineers, and developers from high-profile businesses to meet with our graduate students and share research topics in an informal setting. The annual conference for members, faculty, and final-year PhD candidates is a highlight event in our academic year.

Renowned for his drive and his collaboration in a diverse range of fields, Lai joined Stanford in 1987 and served as chair of the Department of Statistics from 2001 to 2004. He was an accomplished scholar whose research spanned both theoretical statistics and mathematics, as well as their applications in biomedical science, clinical trial design and analysis, cancer research, and other areas. In addition, he served as a mentor, having advised at least 79 students on their doctoral dissertations and seven postdoctoral trainees.

He earned his doctorate in 1971 and joined the faculty at Columbia as a professor of mathematical statistics. Lai met and married Letitia Chow during this time and remained a faculty member at Columbia for more than a decade. In 1986, he was appointed the Higgins Professor of mathematical statistics.

The next year, Lai joined Stanford, where he would teach for the next 36 years. In addition to statistics, he collaborated with researchers in and held courtesy appointments in the School of Medicine, the School of Engineering, and the Woods Institute for the Environment. He also founded the Financial and Risk Modeling Institute in 2012 and served as its director afterward. He was co-director of Stanford Medicine's Biostatistics Core, Stanford Cancer Institute from 2005 to 2016 and its Center for Innovative Study Design from 2009 through 2023.

In addition to his wife, Lai is also survived by his sister, Anna Choi, and her husband, King Fai Choi; older son, Peter Lai, and his wife, Crystal Chen; younger son, David Lai, and his wife, Iris Law; niece Charina Chou and her husband, Jonathan Chou; niece Priscilla Choi; grandchildren, Valerie and Kit Lai; and great-niece, Zoe Chou.

The School of Humanities and Sciences is the foundation of a liberal arts education at Stanford. The school encompasses 24 departments and 25 interdisciplinary programs. It is the university's home for fundamental research, where free, open, and critical inquiry is pursued across disciplines.

This weekend is the 2021 Stanford Commencement. I had the honor of contributing the commencement address for the Statistics and Mathematical and Computational Sciences (MCS) programs. The departmental program is virtual this year, but even without being there in person it is a great privilege to share my advice and well wishes for the graduates - congratulations to the Class of 2021!

The stark challenges of the last year - sometimes physical, sometimes emotional- makes your accomplishments - built on perseverance and resilience - all the more remarkable. So once again, congratulations!

In contrast with the challenges of the last year are the opportunities ahead of you! There has likely never been a better time to be in your seat. Data science, machine learning and AI continue to transform science and industry.

My first experiences in industry followed the well traveled paths to big tech and finance. And these paths are popular for a reason - they often lead to very interesting and fulfilling careers. But after several years one of my mentors from Netflix reached out to me with some surprising career news - he had left Netflix to join a fashion startup called Stitch Fix.

At first I was surprised by the choice - after all, what could be harder to quantify than something that prides itself on being artistic, subjective and even ephemeral? But I was intrigued. I knew the involvement of my mentor meant that something interesting was happening. So I met the team.

What soon became clear was that despite my initial surprise this was a domain primed for data, statistics and algorithmic decision making. Feedback from clients helped us not only learn their preferences, but enabled using that same data to efficiently manage inventory and even design new clothes. Over the years the team and the scope of problems we solved grew - when I left the company earlier this year we had over 140 data scientists and engineers continuing to innovate solutions for our hardest problems. Finding this application of statistics in an unexpected place led to the most fun and important chapter of my career.

The lesson to draw is that the toolset of an MCS or statistics graduate - your toolset - is incredibly valuable even in places beyond the largest employers of quantitative professionals, and in places you might not first expect.

My impulse was to retreat to my training, to seek comfort in the confines of specialization. I had a PhD in statistics - I hoped I could at least be pretty good at that. And staying in your lane makes it easier to not feel like an impostor.

But It was also an optimization problem, a control system problem, a risk management problem, an organizational design problem. By focusing on the business problem, not just the math problem, we were able to draw on the cumulative experience of many disparate disciplines to assemble an efficient assortment of inventory that delighted clients by drawing on our knowledge of both their individual and collective preferences.

Much of the world, including the business world, operates with a great deal of inertia and inherited wisdom. One of the positive sides of the silicon valley disruption ethos is a recognition that we can sometimes do much better by taking a new approach. And in most cases, that new approach is better if it involves a thoughtful quantitative framing and the rigors of scientific thinking.

The crime statistics include alleged offenses, including attempts, reported last year to university staff and police, as well as data from the two years prior. The report indicates where the reported crimes were alleged to have occurred, such as at a student residence, on campus, or on public property immediately adjacent to campus. The report also offers guidance on how to respond to emergency situations like earthquakes, information about the Stanford Community Board on Public Safety, how the AlertSU mass notification system works, and more.

However, community members should be aware of what crimes are being reported and be vigilant to help safeguard themselves, Wade added. Also, sexual assault remains a concern at campuses nationwide, and the community needs to be attentive for the safety and support of survivors.

The increase reflects new guidance by the Department of Education that now counts e-bikes and e-scooters as motor vehicles, and the increasing popularity of these modes of transportation, Wade explained.

In the area of sex offenses, there were 33 rapes reported to Campus Security Authorities, primarily the Title IX Office, last year, up from 30 in 2021 and 15 in 2020; 25 reports of fondling, up from 14 in 2021 and 17 in 2020; and one report of statutory rape following two years in which none were reported. All of the sexual offenses reported last year were reported as occurring on campus, with 23 of the rapes and 10 of the fondling incidents occurring in student residences.

In accordance with the Clery Act, the annual report also notes any cases which the police determined to be unfounded. Last year, two reports of sexual assaults on campus were deemed to have been unfounded and led to criminal charges against the person who reported both false reports, according to a community update.

Stanford encourages those who have been abused to seek support through various resources offered by the university. In 2020, the university created the SHARE Title IX Office as a central resource for redressing and preventing sexual harassment and violence issues experienced by Stanford community members.

Students can also contact the Stanford Confidential Support Team, which offers a 24/7 hotline for urgent support, Counseling and Psychological Services (CAPS) in Vaden Health Services, and the YWCA @ Stanford Program, while faculty and staff can contact the Faculty Staff Help Center.

Stanford encourages anyone who has been the victim of a hate crime or bias-motivated incident to seek support and report the incident. The process for reporting incidents in which a community member feels harmed at Stanford is called Protected Identity Harm (PIH) Reporting. It is managed by staff who work closely with and in the Office of Inclusion, Community and Integrative Learning and the Office of the Dean of Students.

Statistics investigates and develops specific methods forevaluating hypotheses in the light of empirical facts. A method iscalled statistical, and thus the subject of study in statistics, if itrelates facts and hypotheses of a particular kind: the empirical factsmust be codified and structured into data sets, and the hypothesesmust be formulated in terms of probability distributions over possibledata sets. The philosophy of statistics concerns the foundations andthe proper interpretation of statistical methods, their input, andtheir results. Since statistics is relied upon in almost allempirical scientific research, serving to support and communicatescientific findings, the philosophy of statistics is of key importanceto the philosophy of science. It has an impact on the philosophicalappraisal of scientific method, and on the debate over the epistemicand ontological status of scientific theory.
