Distribution Parameter Definition

******************************

All the distributions in the simulator are defined in the same way R language does. 

For example, the user enters the meanlog () and sdlog (s) parameters for all lognormal distributions in the model. Thus, if you want to define  the size of loss to be lognormal with mean 100,000 and standard deviation 100,000, you need to do a conversion calculate first.

To achieve the given size of loss distribution above, you can set the parameter

= meanlog = 11.16636357 and

s = sdlog = 0.832549779

 

since this produces a size of loss X with mean

 

 

This results in Var(X) 2 x 1010 -  1010  and s(X) 100,000.
