Hi all: I have performed relogit with my variables successfully, however, when I keep adding interaction items to see the moderation effect, the error message occurs, It says "matrix has missing values" whereas I am sure the interaction variable has no missing value. Does anyone know how to solve this problem? p.s the two variables are both binary (0,1), thus the interaction term is also binary Thanks! -- RungTai Wu Ph.D Candidate National Tsing Hua University Institute of Technology Management Email: rungtai(a)gmail.com Mobile: 886-910706892 - --- relogit mailing list served by HUIT List Address: relogit(a)lists.gking.harvard.edu Subscribe/Unsubscribe: http://lists.gking.harvard.edu/mailman/listinfo/relogit Relogit mailing list Relogit(a)lists.gking.harvard.edu To unsubscribe from this list or get other information: https://lists.gking.harvard.edu/mailman/listinfo/relogit
