I have so far used the following command glm(formula = s ~ age + gender + gemedu + gemhinc + es_gdppc + imf_pop + estbbo_m, family = binomial(link = "probit")) My question is 1. How do i discard the non significant selection variables (one out of the seven variables above is non-significant) and calculate the Inverse Mills Ratio of the significant variables 2. I...

...re I wish to check for 65*9 values of "yearctry" with each "yearctry" having 2000 observations roughly. Hence I use the glm/probit to look into the selection bias where all my dependant variable "s" are either 0 or 1. The formula *myProbit<- glm(s ~ age + gender + gemedu + gemhinc + es_gdppc + imf_pop + estbbo_m, family = binomial(link = "probit"), data = adpopdata)* is the Heckman selection equation based on all observations without taking into account the fact that each "yearctry" is unique, I want the selection equation to recognise the uniq...

...s (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? Kindly help Thanks in advance Saurav -...

Hi I am working on a panel data, my data are clustered/grouped by the variable "yearctry", I am running the regression below, but I cant make the regression recognise "yearctry" as the panel variable in the regression myProbit<- glm(s ~ age + gender + gemedu + gemhinc + es_gdppc + imf_pop + estbbo_m, family = binomial(link = "probit"), data = adpopdata) Can anyone help me do this please???
