and comparing
the outputs with and without correlation between damage types gives the
results shown in Figure3.29. Also, calculations of the “Probability of Prot”
in the spreadsheet reveal the probability that the average policy cost is less
than the assumed average premium of $800.
The narrower histogram in Figure3.29 represents the no correlation case:
The mean policy cost is not affected by correlation, but the results are clearly
riskier when correlation is present. This is because relatively high (or low)
claims in one dimension will tend to be mat
