Description Details Author(s) References Examples

This package contains functions for calculating severity and generating severity curves. Specifically, the simple case of the one-parameter Normal distribution (i.e., with known variance) is considered.

Package:	severity
Type:	Package
Version:	2.0
Date:	2013-03-27
License:	GPL (>= 2)

There is one function in this package, which is called severity: it (1) computes severity at various discrepancies (from the null hypothesis) for the hypothesis test H_{0}: μ = μ_{0} vs H_{1}: μ > μ_{0}, where μ_{0} is the hypothesized value; and (2) plots both the severity curve(s) and the power curve on a single plot.

*** The difference between this version and previous versions is that one more input is added for additional flexibility: the user is now able to control the hypothesized value of the (unknown) parameter μ. ***
