Hi Maheshkya, If you want to run it please use following queries. 1. StreamingLInearRegression
from Stream4InputStream#streaming:streaminglr(0, 2, 0.95, salary, rbi, walks, strikeouts, errors) select * insert into regResults; from Stream8Input#streaming:streamingkm(0, 2, 0.95,2,20, salary, rbi, walks, strikeouts, errors) select * insert into regResults; in both case the first parameter let you to decide which learning methos you want, moving window, batch processing or time based model learning. BR, Mahesh.
