WebThe p-value is a probability. For the pattern analysis tools, it is the probability that the observed spatial pattern was created by some random process. When the p-value is very small, it means it is very unlikely (small probability) that the observed spatial pattern is the result of random processes, so you can reject the null hypothesis. diamond coat resinWebFeb 18, 2024 · Trend analysis is finding places where something of interest is increasing or decreasing and by how much.
