RiskNormalAlt, RiskNormalAltD
| Description 
 | RiskNormalAlt(arg1type, arg1value, arg2type,arg2value) specifies a normal distribution with two arguments of the type arg1type and arg2type. These arguments can be either “mu”, “sigma”, or a value between 0 and 1 to specify a percentile. 
 | 
| Examples 
 | RiskNormalAlt(5%,1,95%,10) returns a normal distribution with 5th percentile 1 and 95th percentile 10. 
 | 
| Guidelines | With RiskNormalAltD, any entered percentile values are cumulative descending percentiles, where the percentile specifies the probability of a value greater than or equal to the entered value. |
