Hi all,

I intending to employ simple probit, multinomial and Heckman selection model analysis to identify determinants of firms that is applied or not applied for bank credit. I have sample size 300 participants out of population about 18000. I have been asked to check the nature of the data normality (i.e. normal distribution). I tried Skewness and Kurtosis and Shapiro wilk tests. I found the results of Shapiro looks much better than the former test. However, still, I do have many variables that are non-normal distributed (e.g. business sector, age, gender, location, formal education which are <0.05). From your Knowledge and experience, How I could solve the issue of non-normality of these variables. If you think that is normality issue is not a matter for my research analysis, How I could justify this please?

Please, I am seeking for your kind advice.

Many thanks for giving your attention and time in advance
