Hello sir,
Actually, I 'm novice to R programming and currently working on prediction
part for CPU usage log file (attached with mail).
My task is to predict next hour CPU usage by taking "Time" as response and
%user %nice %system %iowait %steal %idle, either all or one as
predictor(s).
Please help me out.
I have attached CPU usage log file with mail.
Please find attachment.
Thank You in advance.
