- between two normal distributions.
-
- Measures the agreement between two normal probability distributions.
- Returns a value between 0.0 and 1.0 giving the overlapping area for
- two probability density functions.
-
- In this `example from John M. Linacre
- <https://www.rasch.org/rmt/rmt101r.htm>`_ about 80% of each
- distribution overlaps the other:

- .. doctest::
-
- >>> N1 = NormalDist(2.4, 1.6)
- >>> N2 = NormalDist(3.2, 2.0)
- >>> ovl = N1.overlap(N2)
- >>> f'{ovl * 100.0 :.1f}%'
- '80.4%'
