This homepage contains the data and programs used in the following paper: Biondini, M.E. A multivariate permutation method for the analysis of landscape spatial patterns (under review). Send any comments you have to Mario E. Biondini: biondini@plains.nodak.edu
The file Sp_An_1D contains the programs and documentation to implement the 1D statistical methods for the analysis of spatial patterns as a function of grain. The file also contains examples of data inputs and outputs. The file is a self-extracted compressed file. To extract the contents double click it from the File Manager window. NOTE: Make sure you read the documentation file ( one_dim.txt) before you use the programs.
The file Sp_An_2D contains the programs and documentation to implement the 2D statistical methods for the analysis of spatial patterns as a function of grain. The file also contains examples of data inputs and outputs. The file is a self-extracted compressed file. To extract the contents double click it from the File Manager window. NOTE: Make sure you read the documentation file ( two_dim.txt) before you use the programs.
The file Data contains the field data (Figs 2-3), in a lotus and excel spreadsheet format, used in the Biondini, M.E. A multivariate permutation method for the analysis of spatial patterns. The file is a self-extracted compressed file. To extract the contents double click it from the File Manager window.
The file MRPPS contains programs, documentation, and examples for the MRPP (LMRPP) and MRBP statistical methods. The file is a self-extracted compressed file. To extract the contents double click it from the File Manager window. Files with extensions *.exe, *.doc, *.dat, *.res are the executable file (double click to run it), the documentation file, example of data set file, and example of result file with data from *.dat.
