I've been trying to match the variances reported by Onyx with those reported by AMOS. Following the example in the AMOS User Guide, I've created a model with four observed variables (recall1, recall2, place1, place2 in the file Attg_yng.xls file) connected to each other with double-headed arrows to determine the covariances of the variables, as is done in AMOS.
The values displayed by Onyx are all different from those displayed by AMOS. For example, the variance of recall1 in AMOS is 5.79 and 110.85 in Onyx. (Excel's VARP function also gives a value of 5.79.) Similarly, the covariance between recall1 and recall2 is 2.56 in AMOS and 121.2 in Onyx (Excel's COVAR gives 2.56).
I'd appreciate an explanation for these differences. Thank you
