Ulf H. Olsson Assignment A) Use the data set in the file: Gra6020week9.psf to estimate and evaluate the measurement model (CFA-model) discussed last week. Is it possible to improve the fit by introducing ”correlated errors” B) Are the measures in the model reliable. Calculate reliability measures for composite measures! C) Same as B) but for the model given in the LISREL file: npv2202.ls8

Ulf H. Olsson Reliability Dear SEMNETERS Hi! The reliability of a construct (Behavioral Intentions-three items) i use in terms of Cronbach's a, is very low (a=32 and a =37 if i delete one of the items). The question is what would you suggest to do in my SEM analysis? I have not yet calculated the Composite Reliability as suggested by Fornell and Larcker (1981) but i was wondering if it would be more appropriate to use a single item (mean average of the three) using the (1- a)xVariance formula for the error variance. Any ideas? thanx Pavlos
