Two models : Comparison based on path coefficient and R²

My question is related to the PLS approach ,and I can rephrase it as follows: If I have 2 PLS models (developed with the same data set): -The first model contains two latent variables: A1 and B. -The 2nd model contains two latent variables: A2 and B (the same B of the model 1). - Both models show th...

Re: Validate or Refute a hypothesis by comparing 4 models

I would model all constructs in one model. Then you can compare the path coefficients from each construct (LA, LB, NLA, NLB) to PERF.
I can't model all constructs in one model : I have problems of validity ==> viewtopic.php?f=5&t=15982&p=26430#p26430

Validate or Refute a hypothesis by comparing 4 models

Hello, I created four models (with same data set) Gv1============>\ LA ========>PERF Gv2============>/ PERF R Square=0,158 LA==>PERF path coef=0,398 Gv1============>\ LB ========>PERF Gv2============>/ PERF R Square=0,281 LB==>PERF path coef=0,530 Gv1============>\ NLA ========>PERF Gv2============>...

One-tailed/Tow-tailed

Hello , In my model (see below ) the path coefficient between two LVs (Gv1 and LA) is 0,57 When I run bootstrapping with a Tow-tailed type test, I find t non-significant: t = 1,92 , Significance Level = 0,05 (t<1,96) But when I run bootstarpping with One-tailed, the link becomes significant: t = 1,6...

Small sample size in PLS

Hello
I have a small sample size : 24 cases
Can I use these 24 cases to validate a model of 4 LV and 3 relations ? see below :

Code: Select all


Gv1============>\
                 LA ========>PERF
Gv2============>/

Fix the problems of discriminant validity

Hi All, I have a simple question: How to fix the problems of discriminant validity?(I have" Fornell-Larcke" & "Cross loadings" invalid , and "HTMT" >0,9 for all LV ) Below my model: 5LV :LA,LB,NLA,NLB,PERF ==>all reflectives R SQUARE =0,357 Path coef LA========(-0,3...
