Hello I am working on a panel data, my panel variable is the variable "yearctry", let me explain what I mean, yearctry is calculated based on the year and the ISD phone code of a country, eg, for the year 2000 say and for country USA say (code = 001), my yearctry variable will then be 2000001, there are 2000 observations (ie 2000 individual responses with yearctry = 2000001), I have 65 different countries in the survey and time span from 2000-2008 ie 9 years.
My question is: How do I make R recognise yearctry as my panel variable when I am running a glm like the one below: > glm(formula = s ~ age + gender + gemedu + gemhinc + es_gdppc + imf_pop + estbbo_m, family = binomial(link = "probit")) What changes/additions do I make to this above probit regression command such that the variable "yearctry" could be passed/assigned as the panel variable?
