If so, please tag it as [self-study]. Mar 30 comment writing down markov chain transition matrix Could you please clarify your question? You ask, "How to write down transition matrix?", yet also include a transition matrix in the statement of your question. Are you saying that the reported matrix is correct, but you don't understand why? Or that you think this matrix is incorrect? Or what?

I have edited my answer accordingly. Mar 24 revised Is a subset $B= {(-\infty,t),t\in \mathbb{R} }$ an event of sample space $\mathbb{R}$? Amended answer to correct an error identified by another user; fixed grammar. Mar 23 answered Is a subset $B= {(-\infty,t),t\in \mathbb{R} }$ an event of sample space $\mathbb{R}$? Feb 3 answered Creating conditional probability distribution Jan 30 comment Determine likelihood that a list of N items contains no negative results after examining X items For an answer to a question that is formally similar to yours, see: stats.stackexchange.com/questions/47286/… Jan 20 comment Measuring representativeness of a (non-random) selection @Thilo: Oh, dear. I suppose I invited that follow-up, so have only myself to blame. Answering would, alas, take a long while. 'Any' stats textbook will cover the topic: see, e.g., W.H. Greene, Econometric Analysis. On 'why not?', I'll recommend a book I find canonical that covers the philosophical and practical problems of hypothesis testing quite well and in depth: Statistical Decision Theory and Bayesian Analysis by J.O. Berger, amazon.com/gp/product/1441930744. Very short answer: I'm interested in using stats to make better decisions under uncertainty. HT doesn't help. Jan 17 comment Measuring representativeness of a (non-random) selection There is a noteworthy economic literature on statistical measurement of race and sex discrimination in, e.g., labor markets, that might be useful. A seminal work is: The Statistical Theory of Racism and Sexism Edmund S. Phelps The American Economic Review Vol. 62, No. 4 (Sep., 1972), pp. 659-661 Published by: American Economic Association Article Stable URL: jstor.org/stable/1806107 Jan 17 revised Measuring representativeness of a (non-random) selection In example: Replaced hand-waving approximate odds ratio with exact calculation; added brief proviso about election procedures for U.S. senators. Jan 17 revised Measuring representativeness of a (non-random) selection Added interpretation of the numerical result as an odds ratio.
