Deal with missing data for the prediction model

Yurie — Tue, 08 Nov 2016 21:10:50 GMT

Hello, I need to build a preditive model for my data. The variables include: year, gender, race, num_cases, location, ageGroup, disease(1:yes, 0:No), maritual_status, charge. We did not collect race data for the first 4 years (coded 99).

1) How can I deal with the missing race data? (It seems the race is significant.)

2) How can I build a model to predict the probability (disease="yes") for the given variables in the dataset?

Very appreciate for any suggestions and help. Thanks.
