multiple comparisons on a between factor
Dear list,
im facing an issue of statistical data analysis that I consider myself
unable to resolve in R so i hope to get some valuable insights from you. i
run an ANOVA with four factors; factor4 is an between factor (two different
groups measured), the others are withins (tested across /all/ subjects).
accordingly, my model looks as follows:
fm1
<-aov(dataSubjects~(factor1*factor2*factor3*factor4)+Error(subject/(factor1*
factor2*factor3))+factor4,data=mydata)
print(sum...

extracting Proportion Var and Cumulative Var values from factanal
...in the followings:
I'm doing factor analysis and I need to extract the loading values and
the Proportion Var and Cumulative Var values one by one.
Here is what I am doing:
> fact <- factanal(na.omit(gnome_freq_r2),factors=5);
> fact$loadings
Loadings:
Factor1 Factor2 Factor3 Factor4 Factor5
b1freqr2 0.246 0.486 0.145
b2freqr2 0.129 0.575 0.175 0.130 0.175

repeated measurements ANOVA
Dear list,
i am setting up a GLM for a repeated measurement ANOVA using the lm and
ANOVA function. my design contains four factors with 5, 5, 2 and 2 (=
14) levels, respectively. the data are stored in a data.frame with six
columns, one for the data themselves and the remainings for the factors
where strings indicate the factor levels in each row. now i would like
to restructure this

ANOVA and confidence intervals plot
Dear *,
I would like to obtain for each factor of my anova model the
"response variable vs factor" plot with means and 95% Tukey HSD
intervals.
I would appreciate any information on how to do that.
Cheers

GLM output for deviance and loglikelihood
It has always been my understanding that deviance for GLMs is defined
by;
D = -2(loglikelihood(model) - loglikelihood(saturated model))
and this can be calculated by (or at least usually is);
D = -2(loglikelihood(model))
As is done so in the code for 'polr' by Brian Ripley (in the package
'MASS') where the -loglikehood is minimised using optim;
res <-
