Local Time Space Kriging

cltsk

Function calls ltsk using cumulatively expanding time space thresholds. This function is useful when predictions are needed using data points at different spatiotemporal intervals. For example, if predictions are needed at a given location for the past 30 days at an interval of 3 days. Instead of using ltsk 10 times, cltsk can compute all 10 values simultaneously.
