Hi, I'm trying to use regresst.jnl, but are having trouble with the case where my independent variable is T (time). I have the variable with name TSC which has 192 lons. 96 lats. 1 depth and 960 times. let p=tsc but how do I set q, when q is really a variable of the same rank as p but has an increase time value for all lons. lats and depths? That is it is an axis rather than an array? Many thanks, Mark.
