This library provides functions for calculations in statistical procedures used in nonparametric methods.

To load:

library(devtools)
install_github("lamcnamara/htr1")
library(htr1)

Functions

findDiffs(xvals,yvals)

• Takes the list of values of X (m) and Y (n) as arguments. Returns ascending list of Y_j - X_i differences, as part of finding the estimator of delta associated with the Wilcoxon rank sum statistic and its confidence intervals.

Example

(Data from Unit II notes, chapter 4 example #1)

modela<-c(17,18,19,22,23,25,26,29,31,33)
modelb<-c(21,24,27,28,30,32,34,35,36,39,41)
findDiffs(modela,modelb)
