Hi Everyone,

 

I have some variables for which i have to impute the missing values. 

 

Please provide your comments as to what kind of techniques are available to perform this task, thanks

 

Regards,

Look at PROC MI?

You can replace missing values with (in approximate order of complexity):

 

  1. a constant (e.g. the mean, median, etc. of your variable)
  2. a predicted value based on other non missing variables (e.g. predict missing weight from the height)
  3. an interpolated value (in time series)
  4. a random value from your variable assumed distribution
  5. a set of random values from your variable assumed distribution (multiple imputation)
