Arguments passed to wmwTest.

Description

Creates a list of arguments that are used for algorithm control and output control.

Usage

wmwControl(nMC = 10^4, epsilon = 10^(-8), 
   digits = 10, latentOutput = c("mw", "po"),
   removeTieAdjustment = FALSE, ncheckgrid=100,
   rcheckgrid=0.1, Vmethod="LAPH")

Arguments

nMC

number of Monte Carlo replications

epsilon

small number, used in uniroot for limits. Rarely needs to be changed.

digits

number of digits for rounding. This is needed so that true ties are treated as ties by the computer, otherwise there can be non-trival errors in the p.values

latentOutput

either 'mw' (Mann-Whitney parameter) or 'po' (proportional odds parameter). Describe output of parameter, estimate, and confidence intervals when latentContinuous=TRUE.

removeTieAdjustment

logical, should tie adjustment be removed? If there are no ties TRUE and FALSE give the same answer. removeTieAdjustment=TRUE is not recommended, only use TRUE when used with correct=FALSE to reproduce method 5 of Newcombe (2006), see example.

ncheckgrid

number of elements in the grid for checking after the uniroot call when tsmethod='abs'

rcheckgrid

range of how far back or forward to look in the checking after the uniroot call when tsmethod='abs'

Vmethod

character to determine the variance function for the asymptotic method. 'LAPH' gives the combination Lehmann alternative and proportional hazards method, and 'PO' gives the proportional odds method Vpo. The methods are nearly identical, but the 'PO' method takes longer, so the default is 'LAPH'.

Value

A list with values of the same name as the arguments of the function.
