The Satterthwaite function can be used to estimate the magnitude of the variance component (sigma_beta)^2,
when the random factor has significant main effects.
Usage
satter(MScoeff, MSi, dfi, alpha = 0.05)
Arguments
MScoeff
coefficients c_1, c_2
MSi
mean squared values
dfi
degrees of freedom
alpha
error probability
Value
vector with 1. estimate of variance 2. degrees of freedom, 3. lower value of 1-alpha confint
4. upper value of 1-alpha confint
Details
Note, the output from the satter() procedure is sigma_beta.
