Total Effects Vs Path Coefficient Values
Posted: Fri Sep 02, 2016 1:41 pm
Hi:
I am a PhD candidate and have just started testing my structural model with SmartPLS3.
I understand that Total Effects is equivalent to the direct + indirect effects of constructs through mediation. But whilst on most occasions the value of the Total Effect from one construct to another it is directly linked to is the same as the value of the Path Coefficient, on other occasions it may not be.
Take for example the Corporate Reputation Extended example in the Primer on Partial Least Squares book (2014). Running the PLS Algorithm returns the values displayed in the model diagram on page 187. Selecting the Total Effects link from the PLS Algorithm Run Report displays the Total Effects calculated: Now whilst many of the Total Effects values match the Coefficients for the direct paths between the constructs (e.g. Attractiveness -> Competence = 0.086 and Corporate Social Responsibility -> Competence = 0.059), some of the figures do not match at all (e.g. Competence -> Customer Loyalty = 0.079 Path Coefficient = 0.06, and Likeability -> Customer Loyalty = 0.564 Path Coefficient = 0.344). The same thing is occurring for the Total Effects within my research model.
Could you please inform me if I am missing something here? I have read the relevant sections in the PLS Primer book and tried to do some research on my own but have not been able to find any answers to this question.
Please help me out with this. Your help is much appreciated :),
