Description
In `ll_invpareto.hpp`
```
nll -= weight(i)*(log(shape) - shape*log(scale) + (shape+1)*log(y) - 2*log(y));
```
Contributor guide
Research direction
Start by reading ll_invpareto.hpp and the surrounding inverse Pareto likelihood implementation. Compare the displayed expression with the inverse Pareto log-likelihood definition and trace how nll, weight(i), shape, scale, and y are used; done means resolving whether the formula is correct and updating the implementation or documenting the confirmed result.
