In PlotNormTest: Graphical Univariate/Multivariate Assessments for Normality Assumption

Graphical plots to assess multivariate univarite assumption of data.

Description

Plots the empirical third/fourth derivatives of cumulant generating function together with confidence probability region. Indication of non-normality is either violation of probability bands or curves with high slope.

Usage

dhCGF_plot1D(x, alpha = 0.05, method)

Arguments

x	Univariate data
alpha	Significant level (default is .05)
method	string, "T3" used the third derivatives, and "T4" uses the fourth derivatives.

Value

Plots

x <- rnorm(100)
dhCGF_plot1D(x, method = "T3")
dhCGF_plot1D(x, method = "T4")
