nsRFA (version 0.3-0)

nsRFA-internal: Internal functions

Description

User-level objects which are for internal use only

ksampleA2 provides the Anderson-Darling test statistic;

nonparboot provides a non-parametric bootstrap;

test.GOFmontecarlo is used to test the type I error of goodness of fit tests GOFmontecarlo.

typeIerrorA2_GOFlaio is used to test the type I error of goodness of fit tests A2_GOFlaio.

fw2 is the approximation of the probability distribution of w (first 2 terms) when $H_0$ is true (Anderson-Darling, 1952); it is used by A2_GOFlaio.

Usage

ksampleA2 (x,cod)
 nonparboot (z,n=length(z))
 test.GOFmontecarlo (parameters, type="NORM", alfa=.05, n=30, N=100)
 typeIerrorA2_GOFlaio (n, T, alfa=0.05, dist="NORM", Nsim=1000)
 fw2 (w)

Arguments

x

vector representing data from many samples defined with cod

cod

array that defines the data subdivision among sites

z

data sample, used for bootstrap

n

length of sample (extracted in nonparboot)

parameters

vector of distribution parameters

type

distribution type: "NORM", "GENLOGIS", "GENPAR", "GEV", "LOGNORM", "P3"

alfa

significance level of the test

N

number of iterations

T

parameters (position, scale, shape, ...)

dist

distribution ("NORM", "LN", "EV1", "EV2", "GEV", "GAM", "LP3")

Nsim

number of iterations, as N

w

transformed test statistic (Laio, 2004)
