Hi,
I'm trying to do an exploratory factor analysis for a uni assignment
but I keep getting this error message coming up
[1] "One of your variables is a constant. Constants are disallowed as
part of a scale."
when I turn the data into a matrix and look at the stats. I've been
told that this means one of the variables doesn't vary much any more,
but I am really stuck on how to sort this out. The code I have used is
summary(prefdata)
prefdata[prefdata>5]=NA
summary(prefdata)
prefdata2=as.matrix(prefdata[3:22])
stats=paf(prefdata2)
[1] "One of your variables is a constant. Constants are disallowed as
part of a scale."
Any help would be greatly appreciated, a few of us are stuck with this
and we're going out of our minds trying to figure out how to fix it!
Thank you so much,
Harriet & the MSc students at Edinburgh
