The tools this\npackage currently provides can be conveniently split into three\nmain sections: (1) calculating persistent homology; (2)\nconducting statistical inference on persistent homology\ncalculations; (3) visualizing persistent homology and\nstatistical inference. The published form of TDAstats can be\nfound in Wadhwa et al. (2018) . For a\ngeneral background on computing persistent homology for\ntopological data analysis, see Otter et al. (2017)\n. To learn more about how\nthe permutation test is used for nonparametric statistical\ninference in topological data analysis, read Robinson & Turner\n(2017) .
