One-way analysis of variance, more so, than other designs follows a very predictable pattern of analysis. Thus, it is possible to write a program that does, just about, everything you would want to do for any particular one-way anova.
The program anova1.do needs to be copied, pasted into the do-file editor and saved to your data directory. To run the program type
Try the findit method first following the
instructions on the screen:
findit effectsize findit tukeyhsd findit tkcomp findit qsturngIf you arre having problems with findit try these commands:
net from http://www.ats.ucla.edu/stat/stata/ado/analysis/ net install effectsize net install tukeyhsd net install tkcomp net install qsturngHere is an example of how to run anova1:
use http://www.phhilender.com/courses/data/cr4a, clear do anova1 y grp
Here is the anova1.do program. You will need to copy it, psate it into your do-file editor, and save in your data directory.
Here is the Stata 11 version.
