I am estimating a discrete choice model in which individuals choose which schools to attend.
I have a large amount of data on individuals and schools. However, each particular school only appears in my data set one or two times since individuals face different sets of school choices based on where they live, etc.
For example, individual A may choose between schools 1, 2, and 3 while individual B chooses between 4, 5, and 6. These choices should provide information on the importance of school attributes, but I cannot determine how to specify this model correctly.
I have followed the advice in this post and ensured that all individual-specific characteristics appear after the |. There is no missing data in my sample. Unfortunately I cannot post my data directly given its somewhat sensitive nature.
