30949 - Second derivative of the hyperbolic tangent function (tanh) is computed incorrectly For analytical procedures that allow program statements, the second derivative of the hyperbolic tangent function (tanh) is computed incorrectly by the compiler that calculates derivatives. If second derivatives are ... http://support.sas.com/kb/30/949.html, 31KB |

18989 - "WARNING: The predicted moment matrix has ## constant elements.." Sometimes PROC CALIS will show the message: WARNING: The predicted moment matrix has ## constant elements whose values differ from those of the observed moment matrix. This means that the model you specified ... http://support.sas.com/kb/18/989.html, 18KB |

24285 - How can I test for equality of parameters in two or more models that contain different predictors? The TEST or MTEST statement in PROC REG does not support hypothesis testing across multiple MODEL statements. However, you can do this testing by using the STEST statement in SAS/ETS PROC SYSLIN. For example, the ... http://support.sas.com/kb/24/285.html, 18KB |

13769 - Orthogonal transformation matrix is incorrect The FACTOR statement in PROC CALIS provides a ROTATE= option which will perform an orthogonal rotation of the factors. However the 'Orthogonal Transformation Matrix' that appears in the output is incorrect. To obtain ... http://support.sas.com/kb/13/769.html, 19KB |
