 Nov11 comment Recommendation for peer-reviewed open-source journal? Thank you, @Faheem! I'll edit this in. Cheers. :-) Nov11 revised Inequality of elements of hat matrix added 7 characters in body Nov11 comment Inequality of elements of hat matrix @Skull: Or more trivially...because it is the square of a real number. :-) Nov10 reviewed Approve suggested edit on Need help comparing graphs Nov10 reviewed Approve suggested edit on Typical sequence of analyzing text Nov10 reviewed Approve suggested edit on How to check if two variables are dependent given a third variable? Nov8 revised What are the most commonly used predictive models when dealing with binary data? added 5 characters in body; edited tags; edited title Nov7 comment What aspects of the “Iris” data set make it so successful as an example/teaching/test data set (+1) Thanks for nicely expanding your comment into an answer. Nov7 reviewed Approve suggested edit on Numerical example for MLE for linear regression model Nov7 reviewed Approve suggested edit on Auto-Regressional & Moving Average Model Formula Properties Nov7 comment How to identify structural change using a Chow test on Eviews? While I believe what you are saying is that the test suggests that the trend does not contain a breakpoint, an edit would help clarify. As a possible alternative to what @gung suggests, you may also edit your answer to include an explanation in your native language. Someone here should quickly be able to help translate it. Cheers. Nov6 comment An inequality involving expectation Hint: Start with a Bernoulli random variable with probability of success $p$. Now compare against a Bernouilli with mass of 1 on 1. What do you notice as you vary $p$? Conclusion? Nov6 reviewed Approve suggested edit on Fixed point iterations for expectation propagation using energy minimization Nov6 answered Flaw in a conditional probability argument Nov6 comment Probability that a continuous random variable assumes a fixed point My point, probably poorly made, is that the argument in the first paragraph is based on the false premise that because the random variable can take on infinitely many values, each individual outcome must have probability zero. This is, of course, incorrect (Poisson, geometric, etc.); the concept of "infinity" is not a strong enough one here, we require uncountability. Nov6 comment Probability that a continuous random variable assumes a fixed point The first paragraph here provides some vague intuition, though the deductive steps are incorrect. There are plenty of distributions that admit an infinite number of values yet each value has strictly positive probability. The second paragraph might profit from a rewording that emphasizes that to each measurement value is associated a (small) interval of possible values of the underlying quantity of interest.
