I have a question about p-values and confidence interval. With 95% confidence intervaly and 0.05 p-value (the WarpPLS defualt), I obtained mostly identical results, but still there were a few cases of disagremment in terms of rejecting or failing to reject the null hypothesis. For example, for a given relationship, (β=0.172, p=0.035<0.05, CI=-0.012 0.357, f2=0.061). All cases of disagreemnt are very similar to the one reported here. <br /><br />Any insights you could kindly provide here? Is CI not robust enough to detect this signficance? or is it the other way around- that p-values is giving false positives. I am aware that the magnitude of the relationship is very small, but not sure which one to report (p-values or CI) and why?
