Correspondence analysis/optimal scaling with ordinal variable
...very low education level, 21 with low education level, etc. I need to compute a score for each area that reflects the education level in this area. This can be done by using correspondence analysis: The scores on the first factor represent an optimal scaling in a certain sense (see the book of Greenacre (1984) "Theory and applications of correspondence analysis" for instance). In other words, I have to transform my ordinal variable "EducationLevel" into a continuous variable "EducationScore". However, this procedure does not account for the fact that one of my va...

[OT] correspondence analysis w/ non-mutually-exclusive ca tegories
Andy, Take a look at Greenacre, Theory and Applications of Correspondence Analysis. He has many example of dealing with all sorts of data. Basically, the technique is relevant for 2-way tables -- MCA is an extenstion. It is not clear in your example whether CA is really appropriate -- you want to make an observation (if at al...

[OT] correspondence analysis w/ non-mutually-exclusive categories
Greetings, again. This is not strictly an R question, so please feel free to ignore it if you like. My question is about the substance of correspondence analysis. Specifically, is it appropriate to use ca on a matrix of values such that the columns and/or rows are not mutually exclusive? To be more detailed: - The standard use of ca is illustrated in the example of corresp() (from MASS):

interpretation of p values for highly correlated logistic analysis
Dear list, I want to perform a logistic regression analysis with multiple categorical predictors (i.e., a logit) on some data where there is a very definite relationship between one predicator and the response/independent variable. The problem I have is that in such a case the p value goes very high (while I as a naive newbie would expect it to crash towards 0). I'll illustrate my problem
