Option	Definition
ALPHA=n	This option requests that confidence limits be constructed for the covariance parameter estimates with confidence level 1- n . The value of n must be between 0 and 1; the default is 0.05
NAMELEN=n	Specifies the length of effect names in tables and output data sets to be n characters, where n is a value between 20 and 200. The default length is 20 characters.
RATIO	This option produces the ratio of the covariance parameter estimates to the estimate of the residual variance when the latter exists in the model .
RIDGE=n	Specifies the starting value ( n ) for the minimum ridge value used in the Newton-Raphson algorithm. The default is 0.3125

To Specify One or More PROC MIXED Options:

Type specific PROC MIXED options in the PROC MIXED Statement Options field.

For example, to specify that names be restricted to 10 characters, type NAMELEN=10 in the text field, as shown below:
