      Poisson regression is the simplest regression model for count data and assumes that each observed count Yi is drawn from a Poisson distribution with the conditional mean ui on a given vector Xi for case i. Therefore, the density function of Yi can be expressed as. ( Exp - u. uY. f Y | X ) = ( ) , where u = Exp ( X. i.

      Most basic statistics books describe three indicators of location: the mean, median, and mode. To compute a mean, you add up all the numbers and divide by how many numbers you have. For example, if you took five tests and your scores were 80, 82, 90, 96, and 96, the mean would be (80 + 82 + 90 + 96 + 96)/5 or 88.8.
