WebSemiDeviation and SemiVariance are implemented as a wrapper of DownsideDeviation with MAR=mean(R).

Webf(r) and D is a return target level. If D is equal to μR = rf(r)dr, then (1) is called the below-mean semivariance of R, while if D is arbitrary, (1) is called the below-target semivariance of R, where D is deﬁned to be the target return. In other words, only the deviations to the left of the returns distribution average, or a ﬁxed return ...
