probability_density_function R Documentation

## Probability density function

### Description

`probability_density_function` evaluates the probability density function of a specific distribution `dist` at a point `x`.

### Usage

``````probability_density_function(dist, x, n, theta, ...)

## S4 method for signature 'Binomial,numeric,numeric,numeric'
probability_density_function(dist, x, n, theta, ...)

## S4 method for signature 'Normal,numeric,numeric,numeric'
probability_density_function(dist, x, n, theta, ...)

## S4 method for signature 'Student,numeric,numeric,numeric'
probability_density_function(dist, x, n, theta, ...)
``````

### Arguments

 `dist` a univariate `distribution` object `x` outcome `n` sample size `theta` distribution parameter `...` further optional arguments

### Details

If the distribution is `Binomial`, theta denotes the rate difference between intervention and control group. Then, the mean is assumed to be √ n theta.

If the distribution is `Normal`, then the mean is assumed to be √ n theta.

### Value

value of the probability density function at point `x`.

### Examples

``````probability_density_function(Binomial(.2, FALSE), 1, 50, .3)

probability_density_function(Normal(), 1, 50, .3)

probability_density_function(Student(TRUE), 1, 40, 1.1)
