 Feb25 comment Normal approximation to the log-normal distribution @RobertIsrael, do you have a reference for your answer above? Citing stackexchange is probably a bit tricky. Sep23 awarded Popular Question Aug18 asked Equivalent to proportionality sign for additive constants Mar28 comment What is the maximum volume of a cylinder that can fit in a sphere of a constant radius? Thanks for the catch. That is now fixed. Mar28 revised What is the maximum volume of a cylinder that can fit in a sphere of a constant radius? Correction motivated by comment. Feb10 awarded Commentator Feb10 comment Repeated convolution of probability distributions I have had a bit of a read and found some interesting distributions. For the sake of computational simplicity, I am interested in distributions with simple PDFs, CDFs and inverse CDFs. The Levy distribution seems a great candidate but has a non-finite moment. Any suggestions for a distribution with analytic PDF, CDF, inverse CDF and finite first moment? Feb10 answered Given $n$-linearly independent vectors how do I find a vector not orthogonal to any of them? Feb10 comment Repeated convolution of probability distributions Thanks for the hint. I found this book, which discusses the topic in more detail: amazon.com/… Feb10 accepted Repeated convolution of probability distributions Feb10 awarded Student Feb10 asked Repeated convolution of probability distributions Jan28 awarded Yearling Dec4 awarded Supporter Dec3 awarded Tumbleweed Nov30 comment posterior density for bayesian estimations The answer is updated to show how to determine the mean and median of the posterior. Nov30 revised posterior density for bayesian estimations Added methods to determine mean, median and mode from normalized posterior. Nov30 comment posterior density for bayesian estimations Yes, the factor of N was missing. Corrected. However, you do not need the full posterior distribution if you use appropriate estimators (e.g. maximize the posterior). You can find more information on page 3 of this publication: arxiv.org/abs/0906.0664 However, the full posterior is needed if you compare different models with one another. Nov30 revised posterior density for bayesian estimations corrected missing lambda factor. Nov30 answered posterior density for bayesian estimations
