Description

This function is for use in my shiny_MVN app to calculate the values for the chi-square plot for assessing normality

Usage

chi_sqQ(df)

Arguments

df	a bivariate data.frame

Value

j the observation number, ordered by the squared distance

d_jsq the squared distance

q_j the chi-square quantiles from the chi-square distribution

Examples

x1 <- c(108.28, 152.36, 95.04, 65.45, 62.97, 263.99, 265.19, 285.06, 92.01, 165.68)
