Fit Same Mean Different Variance Model
Description
Fits a model of the same mean, but different variances model to a set
of several multivariate normal groups by maximum likelihood.
Usage
fitSameMeanDifferentVarianceModel(x)
Arguments
x
list of rmult type datasets
Details
The function tries to fit a normal model with different variances but the
same mean between different groups.
Value
mean
the estimated mean
vars
a list of estimated variance-covariance matrices
N
a vector containing the sizes of the groups
