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)
