rinvchisq {MIfuns} | R Documentation |
Generate inverse chi-square distribution given n, df, and omega estimate
rinvchisq(n, df, omega)
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 |
The rinvchisq
function returns n
omega estimates for use as simulation parameters.
