CVaR Max for Gain. There are M Linear Loss scenario functions (every Linear Loss scenario function is defined by a Matrix of Scenarios). A new Maximum Gain scenarios function is calculated by maximizing losses over -(Linear Loss) functions (over M functions for every scenario). CVaR Max for Gain is calculated by taking CVaR of the Maximum Gain scenarios.
Syntax
cvar_max_risk_g(α,matrix_1,matrix_2,...,matrix_M) |
short call |
cvar_max_risk_g_name(α,matrix_1,matrix_2,...,matrix_M) |
call with optional name |
Parameters
matrix_m is a Matrix of Scenarios:
where the header row contains names of variables (except scenario_probability, and scenario_benchmark). Other rows contain numerical data. The scenario_probability, and scenario_benchmark columns are optional.
is a confidence level, .
Mathematical Definition
CVaR Max for Gain function is calculated as follows
,
where:
is CVaR Risk for Loss function,
M = number of random Loss Functions (See section Loss and Gain Functions):
,
= vector of random coefficients for m-th Loss Function;
= j-th scenario of the random vector ,
is a random function with scenarios:
.
is an argument of function.
Remarks
Every Loss Function is defined by a separate matrix of scenarios and has an equal number of scenarios J.
Probability of scenario is defined by the first matrix.
