rinvchisq {MIfuns}R Documentation

Generate inverse chi-square distribution

Description

Generate inverse chi-square distribution given n, df, and omega estimate

Usage

rinvchisq(n, df, omega)

Arguments

n the number of values to return
df the degrees of freedom for the distribution. This value reflects the uncertainity in the distribution. A reasonable starting point would be a value between the the number of subjects and the total number of observations used to obtain the estimates of the variance-covariance matrix.
omega vector of omega estimates

Value

The rinvchisq function returns n omega estimates for use as simulation parameters.
