Examples: Multilevel Modeling With Complex Survey Datax1y1s1s2x2y2Withinwy2s2y1Betweens1The difference between this example and Example 9.3 is that the modelincludes two random intercepts and two random slopes instead of tworandom intercepts and two fixed slopes and the dependent variable iscontinuous. In the within part of the model, the filled circle on the arrowfrom the covariate x2 to the mediating variable y1 represents a randomslope and is referred to as s1 in the between part of the model. The filledcircle on the arrow from the mediating variable y1 to the dependentvariable y2 represents a random slope and is referred to as s2 in thebetween part of the model. In the between part of the model, therandom slopes s1 and s2 are shown in circles because they arecontinuous latent variables that vary across clusters.In the within part of the model, the | symbol is used in conjunction withTYPE=RANDOM to name and define the random slope variables in themodel. The name on the left-hand side of the | symbol names therandom slope variable. The statement on the right-hand side of the |symbol defines the random slope variable. Random slopes are defined251
