Dear Sir I have been commented by the paper reviewer that disadvantage of using path analysis is the identification of the salient endogenous variables or in other words what are independent and dependent variables (some econometrics test using logit/probit can solve this problem). Sir, I would like...

formative and refelctive index construction

Dear Professors I have query regarding two models - 1) the first order reflective -second order formative - In this case how can the single score for construct can be computed if it measured by 3 items in a reflective way? 2)First order formative-second order formative- I have seen papers in which t...

Hello IN the article "http://davidakenny.net/cm/mediate.htm", its mention that "Sobel test can be conducted using the standardized or unstandardized coefficients. Care must be taken to use the appropriate standard errors if standardized coefficients are used" BUT I have seen many...

bootstrapping-significance-

For finding significance of parameter estimates in smartpls , should the t-value presented in the ouput report of smartpls be taken (after bootstrapping is done ) . OR by bootstrapping procedure as mentioned Shrout and Bolger (2002) i..e if bootstrap is run for 1000 samples , then after putting the ...

Mediation

Sir, In the case of my model, the direct path X--> Y is significant in the model (where there is no mediator) X---->y signifcicant M-->Y significant Then , a mediator is assumed in the model connected as below X---->M----->Y X---->Y In this model. the path X---->M is insignificant; M----->Y is signi...

Hello Sir what if the 1) loading and weight of the formative indicator is negative and significant (checked also for multicollinearity, VIF is less than 2 and also the items are coded properly?). Should that indicator be removed. How should we interpret it. 2)what if loading is negative and signific...

Dear Sir Thank you for the answer. When i ran my model with the control variable (age), most of the paths are significant (all same as in the model without control variable ) except one path. Also the path of age to the dependent variable (DV) is significant. It means that there is direct effect of ...
