Looking for transformation to overcome heterogeneity ofvariances
Peter
You question is difficult to answer without more information about the
distribution of your residuals. Different residual patterns call for
different transformations to stabilize the variance. One very common
form of heterocedasticity is increasing variance with increasing values
of an independent predictor, i.e. the variance of the residuals of y=x
increase as x increases. In this case a

Two Way ANOVA
Hi,
I am using the:
pcf.aov<-aov(meas~op+part, data=pcf.ex2),
command to perform a two way ANOVA. When I save the:
sumpcf<- summary.aov(pcf.aov),
result of the summary.aov command in a variable I need to access the
individual pieces of information in the summary. The summary appears
to be a list and I am having a hard time finding a way to get at the
information in the summary.
