Regression from time series rasters

Discussion created by paxman on Dec 6, 2012

I currently have 20 consecutive rasters of the same area. For every point on the raster I would like to effectively drill down through the series to work out if there is a temporal pattern. Going back to first principles for calculating regressions I have managed to use the raster algebra tool to map the slope of each time series throughout the area. However working out if this is significant is proving to be a lot harder. Is there any tools or scripts available which can do this? I am using 9.3.

Thanks in advance.
