Tidy Randomly Generated Bernoulli Distribution Tibble — tidy_bernoulli • TidyDensity
Description: This function will generate n random points from a Bernoulli distribution with a user provided, .prob, and number of random simulations to be produced. The function returns a tibble with the simulation number column the x column which corresponds to the n randomly generated points, the d_, p_ and q_ data points as well. The data is returned un-grouped. The columns that are output are: sim_number The current simulation number. x The current value of n for the current simulation. y The randomly generated data point. dx The x value from the stats::density() function. dy The y value from the stats::density() function. p The values from the resulting p_ function of the distribution family. q The values from the resulting q_ function of the distribution family.

# Tidy Randomly Generated Bernoulli Distribution Tibble

Source: `R/random-tidy-bernoulli.R`
`tidy_bernoulli.Rd`

This function will generate `n` random points from a Bernoulli distribution with a user provided, `.prob`, and number of random simulations to be produced. The function returns a tibble with the simulation number column the x column which corresponds to the n randomly generated points, the `d_`, `p_` and `q_` data points as well.

The data is returned un-grouped.

The columns that are output are:

- `sim_number` The current simulation number.

- `x` The current value of `n` for the current simulation.

- `y` The randomly generated data point.

- `dx` The `x` value from the `stats::density()` function.

- `dy` The `y` value from the `stats::density()` function.

- `p` The values from the resulting p_ function of the distribution family.

- `q` The values from the resulting q_ function of the distribution family.

## Usage

    tidy_bernoulli(.n = 50, .prob = 0.1, .num_sims = 1)

## Arguments

.n

  The number of randomly generated points you want.

.prob

  The probability of success/failure.

.num_sims

  The number of randomly generated simulations you want.

## Value

A tibble of randomly generated data.

## Details

This function uses the `rbinom()`, and its underlying `p`, `d`, and `q` functions. The Bernoulli distribution is a special case of the Binomial distribution with `size = 1` hence this is why the `binom` functions are used and set to size = 1.
