Subject: maximize command on panel data
Dear Dr. Greene and fellow Limdepers:
I am trying to custom code my own random-parameters panel data code, using Limdep’s maximize command. I thought that I will start with a simple program code, and then take on more complex ones later. However, I quickly hit a wall, even as I tried to specify easy likelihood functions.
In order to specify the correct likelihood function for panel data, I first need to find the likelihood for each group and then sum that over all available groups. I could not figure out how to specify a stratification index group-indicator variable in Limdep’s maximize command. The Limdep volume 2 guide has some examples on how to specify one’s custom likelihood function in the maximize command. However, I could not find any references on how to specify a likelihood function for panel data (using a group-indicator index or some other means).
I will greatly appreciate if anyone can provide me some help on how I can specify a likelihood function for a panel data situation, using Limdep’s maximize command.
