getChiSquare.F {semPower}

getChiSquare.F

Description

Computes the (Wishart-) chi-square from the population minimum of the fit-function: chi-square = (N - 1) * F0 + df = ncp + df. Note that F0 is the population minimum. Using F_hat would give chi-square = (N - 1) * F_hat.

Usage

getChiSquare.F(Fmin, n, df)

Arguments

Fmin

population minimum of the fit-function (can be a list for multiple group models).

n

number of observations (can be a list for multiple group models).

df

model degrees of freedom

Value

Returns chi-square
