Hello everyone, I'm trying to do the conjoint analysis.
This is my script:
library(conjoint)
preferences=read.csv(file.choose())
profiles=read.csv(file.choose())
levels=read.csv(file.choose())
print(preferences)
print (profiles)
print (levels)
Conjoint(y=preferences,x=profiles,z=levels)
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
NA/NaN/Inf in 'y'
In addition: Warning message:
In storage.mode(v) <- "double" : NA introduced by coercion
What I have to do?
