Beginner: Homogenity of Variances
Hello,
for my meta-analysis I try to test if two varainces are equal without

I want to test the variances from dependent and independend
samples.
I assume I can use the var.test procedure for the independent

Thanks in advance

ANOVA procedure on the sufficient statistics
Hi,
I have a two-way anova with unequal cell numbers that I want to analyze.
The problem is I don't have individual observations of the data.
I only have the sufficient statistics (mean, variance, # of observations) for each cell.
Is there any existing function in S-plus that would allow me to do aov() with the sufficient statistics?
The table is like

T2
