R: Skew Student-t distribution

In probability and statistics, Student's t-distribution (or simply the t-distribution) is any member of a family of continuous probability distributions that arise when estimating the mean of a normally distributed population in situations where the sample size is small and the population's standard deviation is unknown. It was developed by English statistician William Sealy Gosset under the pseudonym "S… WebbThe distribution was proposed in [R1]. where 2 < η < ∞, and − 1 < λ < 1 . The constants a, b, and c are given by. a = 4 λ c η − 2 η − 1, b 2 = 1 + 3 λ 2 − a 2, c = Γ ( η + 1 2) π ( η − 2) Γ ( η … WebbThe family of skew- t t distributions is an extension of the Student's t t family, via the introduction of a alpha parameter which regulates skewness; when alpha=0, the skew- t t … gary chapman 5 love languages for children

Otherwise you could transform the data to remove the skew and fit a standard t distribution. Another option would be to calculate moments of your data (e.g. mean, SD) and use them to calculate parameters of your …
