dist-snormFit

Skew Normal Distribution Parameter Estimation

Function to fit the parameters of the skew normal distribution.

snormFit(x, ...)

`x`	a numeric vector of quantiles.
`...`	parameters parsed to the optimization function `nlm`.

snormFit returns a list with the following components:

`par`	The best set of parameters found.
`objective`	The value of objective corresponding to `par`.
`convergence`	An integer code. 0 indicates successful convergence.
`message`	A character string giving any additional information returned by the optimizer, or NULL. For details, see PORT documentation.
`iterations`	Number of iterations performed.
`evaluations`	Number of objective function and gradient function evaluations.
