	Matrix multiplcation
	Hi folks. This is a bit off topic but can anyone show me quickly why any mxn matrix multiplied bu any other nxm matrix always produces a singular mxm matrix, so long as m>n? Thanks xt By Xt - Dec 28 2009 - 3 new of 3 messages

combining Gamma distributions with different k parameters

hi My research recently involved the modeling of photon migration in highly scattering random media. I need some input to understand the path-lengths of the photons (particles under random walk) exiting from the domain. Photon scattering length inside a random medium is modeled by a random variable (RV) of exponential distribution. As a consequence, I believe... more »

Goodness-of-fit, New Technique

Dear Mathematicians, Statisticians and Scientists Everywhere, After 6 months of intensive work, I put between your hands a new project of research about the Relative Goodness-of-fit. This project addresses an important problem of how to choose the best fit from amongst a lot of available models in hand. The outcome is η-Index... more »

	Statistical hypothesis testing
	Hi, I've a question about on statistical hypothesis testing. Let's say I've two approaches A and B and I would like to see if one approach is better than the other. These are my results (p-values) for the statistical testing: A B A - 0.002 B 0.998 - using the alternative hypothesis that the approaches in the first column... more » By Tim Frink - Dec 10 2009 - 1 new of 1 message

	reference for calibration by maximum likelihood for proportional hazards models.
	I'm looking for a reference describing if and how good maximum likelihood is for assessing model fit for a proportional hazards model. I often choose the lowest AIC to pick the best model, but have no firm understanding of how model fit to the data equates to fit of observed vs predicted event times.... more » By TFD - Nov 30 2009 - 1 new of 1 message

	lack of fit
	Dear, I have made a calibration curve and I have determined the lack of fit with excel. Can someone check this file because Fcal > Ftab and I have doubts. Thx By tancho - Nov 2 2009 - 13 new of 13 messages
