sample.sim: Generate random sample with different proportion of outliers and leverage points

Description

Generate random sample with different proportion of outliers and leverage points

Usage

sample.sim(n, p, sig, a1, a2, nn = TRUE, intercept = FALSE)

Arguments

n

number of observations.

p

number of independent variables (predictors).

sig

variance of dependent variable.

a1

proportion of outliers.

a2

proportion of leverage points in outliers.

nn

whether coefficients are non-negative, default TRUE.

intercept

whether intercept is included in model, default TRUE.

Value

y: vector of dependent variable.

x: matrix of predictors with n rows and p columns.

loc: index of added outliers.

beta: vector of coefficients.
