Hi Dehui,
What about my previous suggestion to use dummy variable that indicates time
periods (fixed values 0, 1,2,3...N) for N time periods? I am new to ti

It could probably be added to r.series quite quickly if someone was
willing to provide definitions for "

Good suggestion, and coincidentally I was just looking at it. Am I correct
to assume that to mimic the calculation of slope etc in r.series, I would
need to create a second time series of 'dummy' maps with values 0 for first
time period, 1 for second time period, etc.? I did this in R and it gave

Try MarkusN's r.regression.series in the addons for grass7. It

I have not clue about C programming, but could there be anything in the Gnu
Scientific Library (GSL - http://www.gnu.org/software/gsl/)? See also this
question on StackOverflow:

OK, thanks for the info.

It is not yet implemented... suggestions wh
Hi,
I am using r.series to calculate linear regression slope, offset and
coefficient of determination. But any idea how I can get the standard
deviation t-value and p-value of the slope?
