collinearity

Post by mrzakeri2007 »

hi
for some model that i draw, some coefficients were more than 1, in other soft such amos. but in PLS, i do not have any coefficients more than 1.
which estimate is correct? in Amos or PLS?

In PLS, should i test distribition of data(univariate & multivariate) in PLS?

if between variables, there was collinearity, what can i do about this Var.s?
How do we interpret the estimates?

Hi,

In AMOS I think you have problem "heywood case".

In PLS, should i test distribition of data(univariate & multivariate) in PLS?
For test normality in PLS used IBM SPSS (some method required it).

if between variables, there was collinearity, what can i do about this Var.s?

You cannot interpret before clear collinearity.
