Created for [^1].\n\nUses a Fisher distribution (i.e. Fisher-Von-Mises with p=3) as kernel function. No bandwidth selection. Calculation can be performed\nin chunks to reduce max. memory requirements. \n\n# Coordinates\n\nCoordinates on the sphere must be specified in spherical polar coordinates. The polar angle (theta) must be in the range [0,PI], with\n0 at the north pole, and the azimuthal angle (phi) should be in range [0,2*PI]. Both should be in radians. \n\n# Requirements \n\nThe base module only requires numpy. To run the unit tests, matplotlib and scipy are required. \n\n# Unit tests\n\nThere are two unit tests. The first tests that the Fisher kernel is correctly normalized. The second computes the KDE estimate\nfor a uniform distribution and compares the MISE to the known MISE: for the uniform distribution on the sphere, the MISE can be computed analytically.\nThe parameters for the unit tests are set directly in the scripts. \n\n[^1]: Russell M.B., Johnson, C.L., Gilchrist, S.A.: 2024,\"Investigating the Spatial Relationship of Shield Volcanism with Coronae on Venus\",55th Lunar and Planetary Science Conference,3040,\n      URL: https://ui.adsabs.harvard.edu/abs/2024LPICo3040.2582R\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsag2021%2Fkde_sphere","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsag2021%2Fkde_sphere","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsag2021%2Fkde_sphere/lists"}
