I have such a dataset.

x1 x2 x3 x4

1 1 0 2

0 1 1 10

1 0 1 30

......

x1,x2,x3 are categorical variable(the value can be 0 or 1),and x4 is a continuous variable. x1,x2,x3,x4 is the manifest(measurable) variables which reflect one immeasurable variable. If all of x1-x4 are continuous variables,I can do factor analysis to extract the immeasurable "variable",but some of them are categorical variable which violate the assumptions of factor analysis.So is there anyway to extract the immeasurable "variable" or construct an index based on these variable?

If NOT,then is there any way to classify the cases in to two categories? If all the variables are binary,I can use latent class analysis to do it,but how about binary variables plus countinuous variables?

It is not a R question,I just want some one help me out! Thank you !
