Parameters | Workflows | Minimum Dimension of K Matrix

Minimum Dimension of K MatrixUse this field to specify the minimum dimension of the K matrix to test for finding the optimal compression level of K. The value entered in this field must be a numeric positive integer.If this field is left blank, a minimum dimension of 1 is used and compression is done until all samples form one cluster, which would produce the GLM model fit with no random effect.

Make sure that the Optimized compression method is specified OR the Compress the K matrix box is checked (whichever is available).
