Hi,

it really depends on what your agency wants with that qualitative analysis of residuals.

I would do a histogram of residuals, possibly a histogram of within-subject differences.
Ideally that would amount to something that looks like a normal distribution, but realistically with a low number of subjects it may just look like the teeth of someone who pissed Mike Tyson seriously off. Looking for outliers (looking in this regards means looking, and not quantifying their potential presence) may be another aspect where this could come in handy.

if (3) 4

x=c("Foo", "Bar")
b=data.frame(x)
typeof(b[,1]) ##aha, integer?
b[,1]+1 ##then let me add 1



Best regards,
ElMaestro
