stochdom2: Compute vectors measuring stochastic dominance of four orders.
Description
Stochastic dominance originated as a sophisticated comparison of two distributions of
stock market returns. The dominating distribution is superior in terms of local
mean, variance, skewness and kurtosis respectively, representing dominance
orders 1 to 4, without simply computing the four moment summary measures for the entire
data. Vinod (2008, sec. 4.3)
explains the details. This function uses the output of `wtdpapb'.
Usage
stochdom2(dj, wpa, wpb)
Arguments
dj
Vector of (unequal) distances of consecutive intervals defined on common support
of two probability distributions being compared
wpa
Vector of the first set of (weighted) probabilities
wpb
Vector of the second set of (weighted) probabilities
Value
sd1b
Vector measuring stochastic dominance of order 1, SD1
sd2b
Vector measuring stochastic dominance of order 2, SD2
sd3b
Vector measuring stochastic dominance of order 3, SD3
sd4b
Vector measuring stochastic dominance of order 4, SD4
