Numeric, the confidence level for which the conditional
draw down shall be computed.
softBudget
Logical, whether the budget constraint shall be
implemented as a soft constraint, i.e. the sum of the weights
can be less than one. The default is to use an equality constraint.

Arguments are passed down to Rglpk_solve_LP
Value
An object of formal class "PortAdd".
Details
This function implements a long-only portfolio optimisation for a
minimum conditional draw down at risk (see references below). The
problem can be stated in the form of a linear program and GLPK is used
as solver.
