Hi, I am checking the report of a model I run. I have found Path coefficients both under "PLS/Calculation results" and "Index value results". What is the difference? Which one should I look at if I want to determine the strenght of a predictor on the dependent variable? Thanks a ...

Hi, I have found two different approach suggested in this forum for the same goal. One says that to check discriminant validity i ve to do the Square root of Ave and compare it with LV correlation http://forum.smartpls.com/viewtopic.php?t=293&highlight=discriminant+validity the other says that i...

Hi, I have: - I1 to I12: 12 store attributes (indicators) - S1 to S4: 4 sub-components of the value proposition (LVs - first order) - VP: 1 construct of "overall value proposition" (LV - second order). I m designing a model where S1, S2, S3 and S4 form VP are formed by I1 to I12. As I do n...

Hi Christian, I m not sure this is my case. Both Value and Satisfaction are latent variables. Each of them has 1 manifest indicator (obtained by summated scales). Furthermore when I run the same regression in PLS with the full sample (N=144 cases) Rsquares is equal to 49,8. When I select the sub-sam...

I run a regression Satisfaction=f(value) with SPSS and obtained a Rsquared=0,58.
I run the same regression with PLS and obtained Rsquared=0,999.
The sample is made of 63 cases.
Do you think is it reasonable such difference in Rsuqared? Did I do something wrong?
thanx
Fabio

Can you give me an example of what is "one tail" and what is "two tails"?
thanx

Hi everybody, I am testing a model where Value Proposition, together with Cost are antecedents of Overall Value. The latter, together with Perceived Quality affect Satisfaction. Thus, I obtain two R squared: the first is equal to 37,5 and the second is 49,0. Can I consider such values robust? Is the...
