K Matrix Square Root Variables in K1 Model
Use this field to specify the variables containing columns of the square root of the K matrixin the K1 model, which is a matrix containing kinship coefficients computed using either the Relationship Matrix or K Matrix Compression processes.
This matrix is used as a random effects in the model.
Note: If a Pedigree ID Variable in K1 Model is not specified, this matrix should contain the same number of variables as observations in the input data set. When a pedigree ID variable is specified, this matrix should have the same number of variables as the number of individuals in the largest pedigree in the data set.
To Specify the K Matrix Square Root Variables in the K1 Model:
8 | Specify the Input SAS Data Set. |
All of the variables in the specified input data set are displayed in the Available Variables field.
8 | Examine the list of available variables. |
8 | Highlight the variable(s) listing columns of the square root of the K matrix for the K1 model. To select multiple variables at once, hold down while left-clicking. |
8 | Click to add the highlighted variable(s) to the K Matrix Square Root Variables in K1 Model field. |
