Can you please help me in solving this issue.

Hi @nn_here,
in this case you can use Date to numerical operator to extract parts of your data.

Hi,
Thankyou for the help provided.When i used this operator it's not giving me the result in required format.date field Jul 1,2018 i would like it to split like july (col1),day(col2)2018(col3) as i need to group by on basis of 3 in different cases.i read about date_get(Date, DATE_UNIT_MONTH, 'yyyy/MM/dd') that would satisfy my requirements.But the format is not matching.Can you please help me in this case..

Hi,
Kindly help me in clarifying one doubt regarding missing values in 2 columns.2 columns having more than 2 lakh rows, have more than 1 lakh rows as missing values.Can you please let me know how should be deal with it.To remove the column as such or use replace missing value operator in rapid miner by replacing with sd or avg values..
Also,as part of preprocessing i have used the following operators in rapidminer,
Replace Missing Values -> Remove Correlated Attributes -> Normalize -> Remove Useless Attributes .Is there any more operators i need to verify before getting to actual data processing.
Thanks and regards,
