Computes expected proportional shortfall for a given ditribution
epsg(spec, alpha, ...)
a character string specifying the distribution (for example, "norm" corresponds to the standard normal)
the probabilities associated with expected proportional shortfalls
other parameters
An object of the same length as alpha
, giving expected proportional shortfalls computed.
