File List SynthesiseSpectra2DBetaDetection1000.r -- r code for generating 2D data and determining variance spectra repeatedly from subsamples (<i>n</i> = 1000) Description The SynthesiseSpectra2DBetaDetection1000.r program uses r code to recover spectral exponents from 2D simulated data using repeated hierarchical analysis of variance over a range of nested spatial scales. The method for generating the simulated data using inverse Fourier transforms of 1/<i>f<sup> β</sup></i> weighted random phases and numbers, and the returned <i>β</i>-values are given in Appendix B.
