re: st: syntax for nested two-factor ANOVA

[David Airey <david.airey@vanderbilt.edu>]

I don't think you provide enough information to get the exact anova  
model you want. Since you said nested two factor ANOVA, do you have  
data like this?

brand		company		sold(keep)     	replicates

1               1               1		3
1               1               0		9

2               1               1		etc.
2		1		0

3               1               1
3		1		0

4               2               1
4		2		0

5               2               1
5		2		0

6		2		1
6		2		0

Forgetting if "keep" might be better modeled as a DV, then brand is  
nested in company and brand|company is crossed with keep.

Are you interested in particular brands, or companies, or just trying  
to control for random (nested) data? If in fact you want to treat  
both brand and company as random effects you might look at:

with attention to D.
