I am running a binary regression in SPSS with one dependent variable and 5 independent variables. The results show no values for 3 of these variables but I am very sure that these are significant variables. Is there a systematic error here? Or must I select another regression model? I do get results for these respective variables when working with a different data set.
Thank you Sir for your reply. Actually I have checked this several times, but I get the same results always. What can be a possible explanation for this?
Have you checked the definition of the variables? or maybe their distribution is too abnormal? Also you can check for collinearity among these variables by using a previous correlational analysis.
Hi Priyamvada
Can you post the binary data set you are trying to analyze because, the data must be really binary. Maybe there is an error in the data entry some of the data are not binary.
Please check partial test before simultaneous test. if the result from partial test is no significant, u can't include this variable into simultaneous test.
