Features in Wellness: Pain [0, 1] - no NaNs Illness [0, 0.5, 1] - no NaNs Menstruation [0, 1] - 16 NaNs, filled with 0. Not a big statistical difference, so this is fine Nutrition [0, 0.5, 1] - 837 NaN, filled with 0. Not a useful feature NutritionAdj [0, 1] - 745 NaN, filled with 0. Again not useful USGMeasurement [0, 1] 168 NaN, filled with 0. USG [1.0...] 4382 NaN, not a useful feature TrainingReadiness [0..1] - no NaNs Useful features include Pain, Illness, Menstruation, TrainingReadiness The others either have too many NaNs present to extract any useful meaning or are just unhelpful features to begin with, like Nutrition. Notnormalized_with_0NaN_wellness.csv: - The only feature of significance that had NaN values put into it were Menstruation, as only 16 NaNs were present and wouldn't present any statistical difference either way. - Working in the notnormalized_with_0NaN_wellness csv should be functional, just have to remove any string columns before putting into algorithms as they are not removed in this version
