Unit testing some code and came across this example: `MackChainLadder(auto$PersonalAutoIncurred,alpha=2,tail=TRUE)` I believe this set-up produces unrealistic MackS.E.s
**Is your feature request related to a problem? Please describe.** Per #495, allow for subsequent customization of the `heatmap`. This can probably be done by exposing the pd.style object rather...
chainladder currently relies on `patsy` for Wilkinson formulas (R-style formulas). This gets used in `BarnettZehnwirth` and `TweedieGLM`. However, `patsy` is no longer maintained and is instead replaced by [formulaic](https://github.com/matthewwardrop/formulaic). This...
**Is your feature request related to a problem? Please describe.** `chainladder-python` currently supports tail patterns to 12 months after the end of a triangle for pattern emergence. This is fine...
**Describe the bug** When the key_labels of a triangle are greater than length 1, the `BootstrapODP` puts the triangle in a bad state. **To Reproduce** ```python import chainladder as cl...
**Describe the bug** This shows up when using `IncrementalAdditive` with `BornhuetterFerguson` **To Reproduce** Steps to reproduce the behavior. Code should be self-contained and runnable against publicly available data. For example:...
**Is your feature request related to a problem? Please describe.** There are several pandas deprecation notices with pandas 2.2 and later. These should be handled and silenced. The most common...
**Describe the bug** I think a commit flipped start and end in the Triangle.trend method. However, nothing was done to correct the inputs of either the `Trend` estimator not `CapeCod`...
**Describe the bug** There is some special leap year handling that isn't generalized well. I think it is this line: https://github.com/casact/chainladder-python/blob/master/chainladder/utils/utility_functions.py#L244-L245 This assumes that the format of the of the...
