Shall we remove insignificant relationship?

Post by Jason62 » Thu Nov 22, 2018 1:24 pm

Hi everyone,

I am wondering a question about insignificant paths. After running bootstrapping process to identify the significance among constructs in the mode, I found 3/10 paths are not significant.

So for the report, should I (1) keep that result and make a report on all significant and insignificant relations; or (2) remove all the insignificant relationships and report the new result only?

Thank you for your help!

It depends on what you want to do with your model.
If you are testing hypothesis then you want to keep that and test all in one model and conclude whether they are significant or not.

If you are doing some more exploratory or predictive modelling then deleting may be an option to get a more parsimonious model, especially if you also have theoretical arguments on why a path is unlikely to be important.
