Skewed student-t distribution
WebbStudent's t Student's t-distribution From Wikipedia, the free encyclopedia In probability and statistics, Student's t-distribution (or simply the t-distribution) is a continuous probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small. Webb11 maj 2024 · One way to robustly estimate the mean for a symmmetric distribution is to fit a Student t distribution with a small degrees-of-freedom parameter, say 5. Maybe you can estimate the mean for an asymmetric distribution by fitting a skewed Student t distribution. – Fortranner. May 6, 2014 at 13:34. Let's not conflate "estimator" with …
