'Should I use a heckman model?
I'm currently working on my master's thesis. For my research, I have to measure the impact of two independent variables (amount of infographics and amount of other images) on a dependent variable (amount raised). Also other control variables are included. The data consists of a database containing 2000+ observations, with some missing (NA in R) independent variable values. Someone suggested using a Heckman model for this. I watched a youtube video to make it more clear for myself, but I doubt if a Heckman model is the right way to analyze this. Do you recommend to use the Heckman model for this?
How would you analyze this?
Best regards
