Question:

Bernoulli distribution

Answer:

Discrete probability distribution where the outcome is binary, either 0 or 1.Often, 1 represents success and 0 represents failure. The probability of the outcome being 1 is � and the probability of outcome being 0 is � = 1 − �, where � is between 0 and 1.

Question:

Bias

Answer:

Systematic difference between a true parameter of a population and its estimate. 1 / 4

Question:

Binomial distribution

Answer:

Discrete probability distribution for the exact number of successes, k, out of a total of n iid Bernoulli trials, each with probability p

Question:

Distribution-fitting

Answer:

Determining whether a set of data seems to follow a certain probability distribution, or determining which of several distributions the data is close to.

Question:

Exponential distribution

Answer:

A continuous probability distribution of the time between events. If the number of events in a fixed time follows the Poission distribution, then the time between them has the exponential distribution. The exponential distribution has the memoryless property.

Question:

Geometric distribution

Answer:

Discrete probability distribution of the number of iid Bernoulli trials, each with success probability �, before the first success: Pr(�)= ((1−�)^�)�. Also can be defined as the total number of trials through the first success (so Pr(�)=((1−�)^(�−1))� ). To find the number of trials before the first failure, a similar distribution would be Pr(�)= (�^�)(1−�).

Question:

iid

Answer:

Independent and identically distributed.
