Parameters tab Interest rate movements <-2.0 -1000000 -0.50% -2.0 to -1.5 -2.0 -0.25% -1.5 to 1.5 -1.5 0.00% 1.5 to 2.0 1.5 0.25% >=2.0 2.0 0.50% may i know why the interest rate movement shows X is -1000000 if <-2.0 ? may i know what is the meaning of X here ?
X is as defined in the question, a random number from the normal (0,1) distribution. A large negative has been chosen so that it should always use the -0.5% value for values less than -2. It has been done this way to make the formulae consistent, you could take another approach and that would be fine.
