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.
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 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".
i think conventionally that notation means "multpilied by 10^{12} (i.e. 10 raised to the power 12)" so 3.1491e+12 would mean 3.1491 multipled by 10^{12}
Thank you for that explanation!
Only the soundquality could be better.

simple yet helpful video
Thank you for the good explanation
Thanks for the video!

How do you put more than two variables in Stata for the Oneway ANOVA.
It was extremely helpful!
good morning, how can i have the coefficient of variation in the annova for each factor, using factorial design?

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

Confidence interval stata
Then you use a Kruskal- Wallis test
