Thanks

@ David Hoaglin


for your valuable comments.

Actually I am not filling(extrapolating) all the missing values. I am
only extrapolating the missing values if there are only five or less
missing values.

if i will not extraploate the data , no of observation will be less.

What are your comments on Intrapolation . are people comfortable with
intraploation ( filling the in between missing values).

Regards
Sadia Khalid
