for predictors from certain columns? If so which ones? You also say assume the end of the independent period is 7/27/2010, are you wanting
us to do a model estimation?

Answer or follow-up question 1

"You say make predictors from 5 columns, are you asking for predictors from certain columns? If so which ones? "

No. You can choose the columns yourself.

"You also say assume the end of the independent period is 7/27/2010, are you wanting us to do a model estimation? "

No. You can use that information to compute recency. Recency is defined as t2 minus the maximum purchase date of a customer.
Note that t2 = end of independent period.
