I have imputed a value 2017-09 (or you may put 2017-10) or else it will create a row with missing values. when we merge the transactions data.  There are lot missing values in transaction data as well.  </p>\n\n<p>My question is, that since i received this missing values on the test set, is it a good approach to impute these values before running the regression?</p>\n\n<p>Thanks\nAshish</p>",
