suggested effect sizes values are 0.02(small), 0.15(moderate), and 0.35(large) - so if I get effect sizes approx around 0.02 and 0.03 implies that I can retain those exogenous constructs, since their deletion will not make a substantial impact on the endogenous construct. Am I right?
Partial variance or effect variance measure individual variance predictor to criterion variable. If you result small effect size <= 0.2, indicate you have loss power analysis or specification error-Sympson Paradox.
