Inverse Bernoulli sampling :
Inverse Bernoulli sampling is a method for randomly selecting a binary outcome with a specified probability. This is typically used in situations where we want to simulate a random event, such as the outcome of a coin toss or the success/failure of a particular operation.
To perform inverse Bernoulli sampling, we first need to specify the probability of the desired outcome. For example, suppose we want to simulate the outcome of a coin toss, where heads is the desired outcome with probability 0.5. We can then use the inverse Bernoulli distribution to generate a random number between 0 and 1, with a value less than 0.5 corresponding to heads and a value greater than or equal to 0.5 corresponding to tails.
Here is an example of how inverse Bernoulli sampling could be used to simulate the outcome of a coin toss:
Set the probability of heads to 0.5.
Generate a random number between 0 and 1 using the inverse Bernoulli distribution.
If the random number is less than 0.5, output “heads”. Otherwise, output “tails”.
Another example of inverse Bernoulli sampling is in the context of a medical trial, where the goal is to determine the efficacy of a new drug. Suppose that the probability of the drug being effective is 0.75. We can use inverse Bernoulli sampling to simulate the outcomes of individual patients in the trial, with a value less than 0.75 indicating that the drug was effective for that patient and a value greater than or equal to 0.75 indicating that it was not.
In summary, inverse Bernoulli sampling is a simple and effective way to simulate binary outcomes with a specified probability. It is widely used in a variety of applications, including coin tosses, medical trials, and other scenarios where a random event needs to be simulated.
