Dear colleagues,
I would like to run a cluster analysis on a number of variables. They are
Likert Scale (0 to 10), but they also have a "Don't know' option at the end of
the scale. Apparently, with the 'Don't Know' option in place, they cannot be
considered to be linear or ordinal. How can these variables be analysed using
R? One option would be to use poLC and treat them as categorical variables to
classify the respondents into clusters (latent categorical variable). But is
there a way to treat them as partly ordinal/conitinuous and partly categorical?
Thank you
Jason
