dinvchisq: dinvchisq

In twDEMC: parallel DEMC

Description

density function and for the (scaled) inverse-chi-squared distribution.

Usage

dinvchisq(x, df, scale = 1/df, log = FALSE)

Arguments

x	vector of quantiles
df	degrees of freedom parameter, usually represented as nu
scale	scale parameter, usually represented as lambda.
log	Logical. If log=TRUE, then the logarithm of the density is returned.
