normality: Normality Analysis

In certe-medical-epidemiology/certestats: A Certe R Package for Statistical Modelling

Normality Analysis

Description

Check normality of a vector of values.

Usage

normality(
  x,
  na.rm = getOption("na.rm", FALSE),
  type = getOption("quantile.type", 7)
)

Arguments

x	vector of values
na.rm	Remove empty values
type	an integer between 1 and 9 selecting one of the nine quantile algorithms detailed below to be used.

Default values of na.rm

This 'certestats' package supports a global default setting for na.rm in many mathematical functions. This can be set with options(na.rm = TRUE) or options(na.rm = FALSE).

For normality(), quantile() and IQR(), this also applies to the type argument. The default, type = 7, is the default of base R. Use type = 6 to comply with SPSS.

Examples

x <- runif(1000)
normality(x)

x <- rnorm(1000)
normality(x)

x <- rexp(1000, rate = 3)
normality(x)
