Hi all,
I have a data set with missing value. I would like to estimate those
missing value by using normal ratio method.
Below is part of my data:
AS BL Serdang Jhr Phg Target station
0 0.0 12.8 0.0 23.7 0.0
6 0.0 81.7 0.2 0.0 NA
0 1.5 60.9 0.0 0.0 15.5
1 13.0 56.8 17.5 32.8 6.4
4 3.0 66.4 2.0 0.3 NA
Now I want to replace those NA's, with the estimation values by using this
formula:
weight$v6
<-(weight1*AS)+(weight2*BL)+(weight3*Serdang)+(weight4*Jhr)+(weight5*Phg);
Targetstation
but I still could not replace the NA's. My problem is, how do I replace
those NA's with another value?
Thank you so much for your help and attention.
Regards,
Dila
