other hand, if you want to know about receiver operating characteristic (ROC) curves, a good source of information is Metz (1978). Parenthetical citations are used when you want to cite a reference as a kind of remark at the end of a sentence or phrase. Use \citep for those. If you have two or more parenthetical citations, specify them

The MIXED Procedure - University of Iowa

The MIXED procedure fits a variety of mixed linear models to data and enables you to use these fitted models to make statistical inferences about the data. A mixed linear model is a generalization of the standard linear model used in the GLM procedure, the generalization being that the data are permitted to exhibit correlation and nonconstant
