| ProbYX-package | R Documentation |
Compute confidence intervals and point estimates for R, under parametric model assumptions for Y and X. Y and X are two independent continuous random variables from two different populations.

The package can be used for computing accurate confidence intervals and
point estimates for the stress-strength (reliability) model R = P(Y<X); maximum likelihood estimates, Wald statistic, signed
log-likelihood ratio statistic and its modified version ca be computed.
The main function is Prob, which evaluates confidence intervals and
point estimates under different approaches and parametric assumptions.

Prob(Y, X, "norm_DV", "RPstar", level)
# method has to be set equal to "RPstar".
