tailFactor,StandardAnnualAggLossDevModelOutputWithZeros-method {BALD} | R Documentation |
A method to plot and/or return the predicted tail factors for a specific attachment point.
object |
The object from which to plot the predicted tail factors and return tail factors for all attachment points. |
attachment |
An integer value specifying the attachment point for the tail. Must be at least 1. See Details for more info. |
useObservedValues |
A logical value. If |
firstIsHalfReport |
A logical value or |
finalAttachment |
An integer value must be at least 1 default value is |
plot |
A logical value. If |
expYearRange |
Either a range of years (for example c(1995, 2006)) or one of the keywords “all” or “fullyObs”. |
This method accounts for zero payments. By weighting estimated predicted payments by the probably that the payment is greater than zero.
The tail factor is the ratio of the estimated ultimate loss to cumulative loss at some point in development time. This is a method to allow for the retrieval and illustration of the tail factor by exposure year.
Because the model is Bayesian, each tail factor comes as a distribution. To ease graphical interpretation, only the median for each factor is plotted/returned.

.
For comparison purposes, the function returns three separated tail factors for three scenarios. Theses three tail factors are returned as a list with the following names and meanings:
These are the tail factors estimated when taking the break into consideration.
These are the tail factors estimated when assuming all years where in the post-break regime.
These are the tail factors estimated when assuming all years where in the pre-break regime.
Mainly called for the side effect of plotting. Also returns tail factors for all attachment points through finalAttachment
. See Details. Returned invisibly.
