Package ‘Spbsampling’ August 24, 2020 Title Spatially Balanced Sampling Version 1.3.4 Description Selection of spatially balanced samples. In particular, the implemented sampling de- signs allow to select probability samples well spread over the population of interest, in any di- mension and using any distance function (e.g. Euclidean distance, Manhattan dis- tance). For more details, Benedetti R and Piersi- moni F (2017) <doi:10.1002/bimj.201600194> and Benedetti R and Piersi- moni F (2017) <arXiv:1710.09116>. The implementa- tion has been done in C++ through the use of 'Rcpp' and 'RcppArmadillo'.

To have constant inclusion probabilities πi = n=N, where n is sample size and N is population size, the distance matrix has to be standardized with function stprod. Usage hpwd(dis, n, beta = 10, nrepl = 1L) Arguments dis A distance matrix NxN that specifies how far all the pairs of units in the popu- lation are.
