Create variable ndyprmpm2_5
Process Step
Description Compute target variable ‘ndyprmpm2_5’ based on ‘ aqiwdpm2_5 ‘ , ‘region’ and ‘date’. The number of days during the last thirty days from date, date included, where ‘aqiwdpm2_5’ = ‘3’ ‘Poor’ or ‘aqiwdpm2_5’ = ‘4’ ‘Very poor’ or ‘aqiwdpm2_5’ = ‘5’ ‘Extremely poor’ becomes the value of the target variable
This step uses a script written in Python3.
