Thank you for that explanation!

Only the soundquality could be better.

Stata does not have an official command to compute the Welch or Brown-Forsythe statistics. One possibility you may consider is fitting a model with -regress- an the -vce(robust)- option to calculate robust standard errors. You can then use -test- or -contrast- to obtain a test using these robust standard errors.

How do you put more than two variables in Stata for the Oneway ANOVA.

good morning, how can i have the coefficient of variation in the annova for each factor, using factorial design?

[Bennyapple]

if this is not supported by the svy command how do we run ANOVA results that are weighted?

[Lixatto]

I think when your variances are different you can use Brown-Forsythe and Welch (Robust mean comparison). But I don't know where there are in Stata... =/

what happend when the data aren´t normal or yours variances are different?

What does it mean in your ANOVA table when the values for SS between groups, within groups states for example 3.1491e+12?
I don't understand the "e+12".
