missing data problems

[Eddie Pengma]

Dear All,

I am doing some empirical data analysis these days and in this dataset, there are lots of missing data, especially for the string variable. Actually, I do not want to drop these missing data, and I also want to use their existing data for other variables. Can you give me some tips on dealing with missing data issues, for string variable and numeric variable resepctively?

Best regards,

Eddie

I'm not sure what you can do for string variables, but here are some suggested introductory and intermediate readings for dealing with missing data in numeric values, in alphabetic order.
