Trend analysis: quantify the combined probability of a spatialy distributed trend

Discussion created by trevor-keenan on Sep 9, 2013
Hi all,

I have a map of trends across the eastern US. Each pixel has a trend value, along with an associated p-value for the trend for each pixel.

The p-values are not all significant, but the trends are all positive, so the joint probability of the trend must be a lot higher than each individual p-value.

Does anyone have any suggestions re: methods/tools to calculate the joint probability of the trend?

Looking forward to your suggestions!
