qDiptab: Table of Quantiles from a Large Simulation for Hartigan's Dip Test

Description

Whereas Hartigan(1985) published a table of empirical percentage points of the dip statistic (see dip) based on N=9999 samples of size $n$ from $U[0,1]$, our table of empirical quantiles is currently based on N=100'001 samples for each $n$.

format

A numeric matrix where each row corresponds to sample size $n$, and each column to a probability (percentage) in $[0,1]$. The dimnames are coercable to these values, see the examples.

dip, also for the references.

Examples

data(qDiptab)
str(qDiptab)
## the sample sizes `n' :
(nn <- as.integer(rownames(qDiptab)))
## the probabilities:
P.p <- as.numeric(print(colnames(qDiptab)))

## This is as "Table 1" in Hartigan & Hartigan (1985) -- but more accurate
ps <- c(1,5,10,50,90,95,99, 99.5, 99.9)/100
tab1 <- qDiptab[nn <= 200,  as.character(ps)]
round(tab1, 4)
