Hello,   We are trying to analyze an open source survey data to find a correlation between categorical dependent and independent variables. We have performed chi square tests to test the null hypotheses and also would like to perform logistic regression to find a correlation between these variables. However, I understand that logistic regression is predictor model, more specifically, binary classifier model which means that it tries to assign exactly one of the 2 classes to every observation and it produces probability with which each observation belongs to each class. It can be more accurately applied to variables which have exactly 2 answers like yes or no; survived or dead; male or female and such observations.   So now, according to our data, this does not hold true as we have many possible answers to the dependent variable like fair, poor, good, very good and excellent. However, we are considering only 2 answers namely poor and fair for our analysis.   Can we use logistic regression for correlation of such a data-set? We have also used Spearman Rank Correlation Coefficient to determine the correlation   Also, is there any way to correlate the 'c value' from the logistic regression and the Spearman Rank Correlation Coefficient?   Any guidance on this is highly appreciated.   Thank you in advance.   -KS. ...
