Brief Name

Short Description

Root Mean Squared Error

st_pen

Root Squared Error of Linear Loss scenarios calculated with Matrix of Scenarios or Expected Matrix of Products. By definition, it is an average of squared  loss scenarios.

Root Mean Squared Error Normal Independent

Remarks

1.Functions from the standard group are calculated with double precision.
2.Any function from this group may be called by its "brief name" or by "brief name" with "optional name"
The optional name of any function from this group may contain up to 128 symbols.
Optional names of these functions may include only alphabetic characters, numbers, and the underscore sign, "_".
Optional names of these functions are "insensitive" to the case, i.e. there is no difference between low case and upper case in these names.
