The normal distribution is a probability distribution that follows the graph of a bell curve: the most common outcomes are clustered around the mean, with probability tapering off towards the ...

In a number of situations we are faced with the problem of determining efficient estimates of the mean and variance of a distribution specified by (i) a non-zero probability that the variable assumes ...
