Tidy Randomly Generated Bernoulli Distribution Tibble
Source:R/random-tidy-bernoulli.R
tidy_bernoulli.RdThis 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_numberThe current simulation number.xThe current value ofnfor the current simulation.yThe randomly generated data point.dxThexvalue from thestats::density()function.dyTheyvalue from thestats::density()function.pThe values from the resulting p_ function of the distribution family.qThe values from the resulting q_ function of the distribution family.
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.
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.
