Hello everyone,I am Shivanjan Chakravorty, I am an 8th semester Computer Science Engineering student. I've been using Python as my primary language for quite a long time now. And I wish to contribute to pystatsmodel package for GSoC by adding all the Multi Criteria Decision Analysis methods listed in MCDA Wikipedia page here. I wish to provide all the methods listed in the Wiki Page and make it a core part of pystatsmodel as this has a wide range of application in multiple domains. I am open to suggestions and discussion on this. Thank you.
