I employed fractional response regression proposed by Wooldridge and Papke for my study as the dependent variable is a proportion (remaining/whole) and is between 0 to 1 (including 0 and 1). I want to know what are the assumptions that must be tested? As such, OLS regression has mainly 3 assumptions such as homoscedasticity, absence of autocorrelation and normality. Similarly, what are the post estimation tests valid for fractional response regression? I used "fracreg" command on Stata to obtain my results.
