Abstract:
|
It is usual to choose to make the bins in a histogram all have the same width. One could also choose to make them all have the same area. These two options have complementary strengths and weaknesses; the equal-width histogram oversmoothes in regions of high density, and is poor at identifying sharp peaks; the equal-area histogram oversmoothes in regions of low density, and so does not identify outliers. We describe a compromise approach which avoids both of these defects.
