Computes the profile log likelihood over a grid of values of \(\psi\) for various parameters, including return levels.
Arguments
- psi
- grid of values for the parameter to profile 
- model
- string; choice of extended eneralized Pareto model. 
- param
- string; parameter to profile 
- mle
- a vector or matrix with maximum likelihood estimates of - kappa,- scale,- shape. This can be a matrix if there are multiple threshold
- xdat
- vector of observations 
- thresh
- vector of positive thresholds. If - NULL, defaults to zero.
- plot
- logical; if - TRUE, returns a plot of the profile log likelihood
- method
- string giving the optimization method for the outer optimization in the augmented Lagrangian routine; one of - nlminbor- BFGS
- p
- tail probability for return level if - param="retlev".
