ERROR:MATRIX IS singular default GSL error handler invoked when conducting subgroup analysis
Dear all
When I conduted the subgroup analysis by click "mean", chose the corresponding covariate(the moderator). But it met problems, shown "ERROR: matrix is singular Default GSL error handler invoked"
How to conduct the subgroup analysis since no manual for it
It would be thankful if anyone could give me a solution to sort out this issue. Thanks in advance.
