Total effects : unexpected negative signs

Post by chrisrup » Mon Sep 22, 2014 4:26 pm

I computed a model of an old project again. First I got slightly different values, but what is really strange, is that I have negative signs for total effects, where this is absolutely not plausible. A simple example: in the path coefficient output I have a positive sign for A-->B and in the total effect output I get a negative sign, although it's the same path A-->B.

Is this a common problem or have I done something wrong?

This issue occured due to some changes in matrix computations when switching from 3.1.4 to 3.1.5. Things will be fixed in 3.1.6
