| + | ==== financial module ==== | ||
| + | * damage ratio for specific event s multiplied by the building replacement value to obtain the loss distribution | ||
| + | * this module computes the combined loss distribution of all buildings through a process known as convolution | ||
| + | * 2 loss distributions for 2 locations -> process is completed for all other possible combinations and thus the convolved loss distribution for the total loss of the two locations is obtained | ||

| + | ====== risk quantification ====== | ||
| + | ==== expeedance probability curve ==== | ||
| + | * EP Curve | ||
| + | * describes the probability that various levels of loss will be exceeded | ||
| + | * an EP curve is generated by running the catalogue against exposure (buildings) and obtaining losses for each event and year | ||
| + | * //The events are then grouped by year (the reader should recall at this point that each simulated event has a simulated year to which it is associated) to determine the loss-causing events for each year. The total mean loss for each year is then found by adding the mean losses for each event together. It should also be noted that the mean of the convolved loss distribution for a year is the same as the sum of the mean losses of each event in that year. The losses are then sorted in descending order and plotted to give the exceedance probability and corresponding loss at that probability. The EP curve is the basis upon which insurers estimate their likelihood of experiencing various levels of loss | ||

| + | * possibility to invert this curve -> will get return period | ||
| + | * exceedance probability 1 % == "1 in 100 years storm" | ||

| + | ==== percentiles ==== | ||
| + | * One way for insurers to assess the potential payouts that could be required at various return periods is through plotting percentiles around the EP curve | ||
