Unexpected (standardized residuals reported if not less than) = 3 |
This is for 32-bit Facets 3.87. Here is Help for 64-bit Facets 4
This controls the size of the smallest standardized residual listed as unexpected in Table 4 of the output results file. When the data fit the model, about 5% of standardized residuals are outside ±2, and about 1% are outside ±3. Residuals concentrated on particular elements show local misfit, which may not be widespread enough to affect the summary fit statistics. At most, T4max= residuals will be reported.
Example 1: To request all residuals with absolute value greater than or equal to 2.5 in Table 4, sorted by in descending order, type
Unexpected=2.5
Usort= u
Example 2: To output residuals for all elements in Table 4, type
Unexpected=0
Caution: Requesting all residuals can produce voluminous output! It may be more useful to produce a Residual file, see Residualfile=
