## Detailed Description

Loss Distribution for Homogeneous Pool.

Loss Distribution for Homogeneous Pool

Loss distribution for equal volumes but varying probabilities of default.

The method builds the exact loss distribution for a homogeneous pool of underlyings iteratively by computing the convolution of the given loss distribution with the 'loss distribution' of an additional credit following
