ltsk: Local Time Space Kriging

Implements local spatial and local spatiotemporal Kriging based on local spatial and local spatiotemporal variograms, respectively. The method is documented in Kumar et al (2013) <https://www.nature.com/articles/jes201352)>.

Local Time Space Krigingltsk-package
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.cltsk
