Between school and family duties, I’ve been finding it hard to find any time to indulge in olympiad math blogging 😦 At the same time, I’ve missed the feeling of typing up stuff that I find interesting and sharing it with others.

To that end, I just started a new blog Statistical Odds and Ends! The idea for this began when I found myself spending a lot of time googling relatively simple things in the course of my studies and research. For example:

- Why does the ridge regression solution exist and why is it unique?
- What is the formula for the matrix such that the projection of the vector onto the column space of a matrix is ?
- Can I switch supremums and expectations and still have equality? If not, can I get an inequality instead?
- How can I derive the bias-variance decomposition?

I was often googling for the same things over and over again, and trying to re-understand what others were writing.

Hence the idea of Statistical Odds and Ends. The blog will be a place for me to pen down my understanding of these statistical tidbits, and to share it with others. Hopefully some of the material there will be of interest to you! If the content is relevant to this audience, I will cross-post over on this blog too.
