Compute the posterior probability given a Bernoulli distributed likelihood

In a coin flip, we would like to compute p(theta|Data), where theta is the underlying parameter. The prior follows a beta distribution with parameters a and b. The likelihood follows a Bernoulli distribution which gives us the probability of…

Coin tossing simulation unexpected probabilities

This is a script I wrote to simulate a coin toss game that ends in a given fixed sequence of outcomes (tosses are either ones or zeroes). This fixed sequence characterizes the game. For example, coin_series('01') simulates a series of tosses that…

Statistics - Standard Deviation of test statistic # of heads - # of tails

I have a question concerning the following N is the no. of coin tosses H is the no. of heads obtained T is the no. of tails obtained Q = H-T N = 100 H = 63 T = 37 Q = 26 Is this significant evidence that the coin is unbiased? what is the standard…

Generate a random number using coin flips while guarenteeing termination

The usual method to generate a uniform random number 0..n using coin flips is to build a rng for the smallest power of two greater than n in the obvious way, then whenever this algorithm generates a number larger than n-1, throw that number away and…
