I've skewed 30 items for 90 cases (subjects). Skewness of variables in range 1.7 up to 3.00. Is that true? and what is the best method to test it?
I test a structure equation model of five variables 2 of them independent and 2 moderate and one is dependent. the relationships in mplus are D by d1 d2; R by r1 r2; A by a1 - a4; M by m1 m2; S...
