chainladder - Property and Casualty Loss Reserving in Python
------------------------------------------------------------

This package gets inspiration from the popular `R ChainLadder package`_.

This package strives to be minimalistic in needing its own API. Think in
`pandas`_ for data manipulation and `scikit-learn`_ for model
construction. An actuary already versed in these tools will pick up this
package with ease. Save your mental energy for actuarial work.
