MNSQ= show mean-square instead of t-standardized fit statistics = Yes |
The mean-square or t standardized fit statistics are shown in Tables 7, 11 to quantify the unexpectedness in the response strings, and in Tables 4, 5, 8, 9 for the fit plots.
MNSQ=N Show standardized (ZSTD) fit statistics. ZSTD (standardized as a z-score) is used of a t-test result when either the t-test value has effectively infinite degrees of freedom (i.e., approximates a unit normal value) or the Student's t-statistic distribution value has been adjusted to a unit normal value.
MNSQ=Y Show mean-square fit statistics. Use LOCAL=L for log scaling.
