I have a few questions as a new user. 1. What is a Julia ecosystem? I am guessing it is something to do with the version of the language.
I am trying to construct a regression with panel data and was told by someone to use the following (for a fixed effects model):
data = CSV.read(“wagepan.csv”);
categorical!(data, [:nr, :year, :married, :black, :hisp, :educ])
fm = @formula lwage ~ exper + expersq + married + union + (absorb = nr + year)
model = EconometricsModel(fm, data)
and they mentioned that the reason mine is not working is because I am using JuliaPro hence my first question. Is there a way to use JuliaPro to run the “categorical!” function? and if I were to run the above in JuliaPro what packages will I need.
