epois: Poisson Distribution Estimation

In matheuscastro43/finiteMix: Finite Mixture Models

Poisson Distribution Estimation

Description

Estimates parameters of a univariate Poisson Distribution with maximum likelihood.

Usage

epois(data, plot.it = TRUE, empirical = FALSE, col.estimated = "orange",
      col.empirical = "navy", ...)

Arguments

data	vector containing the sample as rpois.
plot.it	logical, TRUE to plot the histogram with estimated distribution curve.
empirical	logical, TRUE to add the empirical curve ("Kernel Density Estimation") in the plot.
col.estimated	a colour to be used in the curve of estimated 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 = rpois(n = 1000, lambda = 6)

## And now, estimate the parameters, using the 'data' list.
epois(data)

## Not plotting the graphic.
epois(data, plot.it = FALSE)

## Adding the empirical curve to the graphic.
epois(data, empirical = TRUE)

## Changing the color of the curves.
epois(data, empirical = TRUE, col.estimated = "pink", 
      col.empirical = "red3")

## Using "..."
epois(data, empirical = TRUE, col.estimated = "pink", 
       col.empirical = "red3", axes = FALSE)
