I am pretty new to econometrics, and I am thinking about substituting a continuous variable (say assets for a company) with a categorical one containing a number based on which quintile the continuos value was (so 1-5). Obviously doing so I will lose some information however I was hoping that doing so would semplify the interepretation of an interaction variable made of the original continuos variable and of another continuos variable. Especially as I am going to plot a marginsplot (in STATA). I wanted to ear the opinion of someone more experienced and if this is a good/ feasible idea or it will backfire in some way.
Thanks in advance
