DEVELOPMENT OF A CORRELATION PROGRAM

A statewide correlation program aimed at improving test method reproducibility is discussed. Statistical methods such as analysis of variance, regression analysis, principal components analysis and nonparametric analysis are used for developing an integrated program of interlaboratory testing. Four computer programs using these methods are presented. Guidelines for conducting a correlation program are given.
