The family of skew-ttt distributions is an extension of the Student'sttt family, via the introduction of a alpha parameter which regulates skewness; when alpha=0, the skew-ttt distribution reduces to the usual Student's ttt distribution. When nu=Inf, it reduces to the skew-normal distribution. When nu=1, it reduces to … Visa mer Density function, distribution function, quantiles and random number generation for the skew-ttt(ST) distribution Visa mer Density (dst), probability (pst), quantiles (qst) and random sample (rst) from the skew-ttt distribution with given xi, omega, alpha and nuparameters.

The distribution was first introduced by Panayiotis Theodossiou [1] in 1998. The distribution has since been used in different applications. jesus gazol
