rlindley_mix: Random Generator of a Lindley Mixture

In matheuscastro43/finiteMix: Finite Mixture Models

Random Generator of a Lindley Mixture

Description

Generates random samples of a univariate Lindley Mixture.

Usage

 rlindley_mix(n, pi, beta, plot.it = TRUE, empirical = FALSE, col.pop = "red3",
              col.empirical = "navy", ...)

Arguments

n	number of observations.
pi	vector of mixture weights.
beta	vector of parameters.
plot.it	logical; if TRUE (default), plot the histogram with estimated distribution curve.
empirical	logical; if TRUE, add the empirical curve ("Kernel Density Estimation") in the plot.
col.pop	a colour to be used in the curve of population density.
col.empirical	a colour to be used in the curve of empirical density.
...	further arguments and graphical parameters passed to hist.

Examples

## Generate a sample.
data = rlindley_mix(n = 1000, pi = c(0.6, 0.4), beta = c(2, 3))

## Sample vector.
data$sample
## The histogram of the sample with population density curve.
data$plot

## Not plotting the graphic.
rlindley_mix(n = 1000, pi = c(0.6, 0.4), beta = c(2, 3), plot.it = FALSE)

## Adding the empirical curve to the graphic.
rlindley_mix(n = 1000, pi = c(0.6, 0.4), beta = c(2, 3), plot.it = TRUE, 
             empirical = TRUE)

## Changing the color of the curves.
rlindley_mix(n = 1000, pi = c(0.6, 0.4), beta = c(2, 3), plot.it = TRUE,
             empirical = TRUE, col.pop = "blue",col.empirical = "green")

## Using "...".
rlindley_mix(n = 1000, pi = c(0.6, 0.4), beta = c(2, 3), breaks = 300)
