chainladder.Chainladder#
- class chainladder.Chainladder#
The basic determinsitic chainladder method.
- Parameters:
- None
- Attributes:
- X_:
returns X used to fit the triangle
- ultimate_:
The ultimate losses per the method
- ibnr_:
The IBNR per the method
- full_expectation_:
The ultimates back-filled to each development period in X replacing the known data
- full_triangle_:
The ultimates back-filled to each development period in X retaining the known data
