We use the aforementioned eight factor models and report the number of significant factor coefficients of the different factor models in Table 2.
The context of the sentence is that I ran 25 regressions using 8 models, respectively. Every right-hand variable have 25 coefficients among which some are not significant. I need to report the number of significant coefficients for such a variable.
Really appreciate any help.
