WebThe following example compares the AR(1) and Toeplitz models above. Both structures have constant variance, but under the AR(1) structure the correlations change over time according to the power function. The Toeplitz structure does not have this requirement. Consequently, the AR(1) structure is a special case of the Toeplitz structure. WebTable 1. Pearson Correlations for Pre-test Solutions Section The polychoric correlation can be obtained using PROC FREQ, then the output data can be manipulated to take the form of a correlation matrix that can be read into other procedures such as PROC FACTOR and PROC IML1. 1 This section of code was inspired by the very helpful SAS FAQ: WebExample 2.2 Computing Correlations between Two Sets of Variables.
