>In CASA, as in every other research centre, working papers are what they

>In journals like Environment and Planning B, and Computers, Environment

>normal way which is based on three referees comments and invariably revisions.
>I won't make any comment on the comment except to say the issues on

>to data does not imply that we need to meet normality assumptions, we only
>need to do this if we examine the variances of the errors. One can fit
>straight lines to data without invoking probability theory.
