Description
Software - covsep-1.0.1.tar.gz : R package implementing the methodology of the paper. #### Data for reproducing the Numerical simulations: - reproduce-sims.R: R script to reproduce the simulation studies; WARNING: the simulations take a lot of time. - SIM2016a-SIM12feb.RData: results of the simulation studies, and parameters to reproduce them. - grid-sims2.RData: results of the simulation studies (Figure 5 and Figures S2 & S3 of the supplement), and parameters to reproduce them. - sim_function.R: function performing the simulation studies #### Data application: - Acoustic_Data_part1.RData: R workspace containing the preprocessed log-spectrograms considered in the phonetic application. (part 1) - Acoustic_Data_part2.RData: R workspace containing the preprocessed log-spectrograms considered in the phonetic application. (part 2) - Info_Acoustic_Data.txt: text file with information about the phonetic sounds. This includes the language, the word being pronounced and the gender of the speaker. - separability_Acoustic_Data.R: script to replicate the test for separability for the phonetic data as described in the manuscript.
