IPMA - Include LVs with non-significant total effect ?

Post by agalvez »

Hi

When asessing structural model relationships, what happen if some LVs’ total effects (importance) are non-significant explaining the target LV? Do I have to include them in the IPMA? Does this make sense?

Another issue... Negative total effects are included in the map as "negative" or as "absolute values" ? I think I have to include them as absolute values, since the purpose is to compare their relative importance with other constructs. Is this correct?

Thank you in advance

Insignficant total effects and negative ones (when you expect positive ones) are not reasonable for running an IPMA.

Thank you Prof. Ringle.

Then, insignificant total effects are excluded from the IPMA analysis, focusing on the significant ones.

Best regards.
