spatialpred

A heuristic method to perform spatial predictions. The method consists of a local interpolator with stochastic features.
It allows to build effective detailed maps and to estimate the spatial dependence without any assumptions on the spatial process.

Tools designed to perform and evaluate cluster analysis (including Tocher's algorithm),
discriminant analysis and path analysis (standard and under collinearity), as well as some
useful miscellaneous tools for dealing with sample size and optimum plot size calculations.
A test for seed sample heterogeneity is now available. Mantel's permutation test can be found in this package.
A new approach for calculating its power is implemented. biotools also contains tests for genetic covariance components.
Heuristic approaches for performing non-parametric spatial predictions of generic response variables and
spatial gene diversity are implemented.
