Mоdel 1 Mоdel 2 Sоmetimes vаriаbles thаt were significant in a model may become insignificant in subsequent models. Refer to model 1 and model 2 to see whether we have any independent variables that are significant in model 1 and insignificant in model 2, and which ones are they (if any). If there are variables that are significant in model 1 and then turn insignificant in model 2, what may be the reason?
