A statistical procedure used to test the hypothesis that a particular probability distribution adequately fits an observed set of data.
The mean return is a key metric in security analysis, representing the expected value or average of all possible returns on investments within a portfolio. It is also used in capital budgeting to determine the mean value of the probability distribution of possible returns.
The Poisson distribution is a type of probability distribution that typically models the count or number of occurrences of events over a specified interval of time or space.
A random variable is a fundamental concept in statistics used to describe quantities that have no fixed value but instead are subject to variability due to random phenomena.
Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a set of values. It is widely used in situations where comparing variability between different data sets or understanding the consistency of data points is crucial.
