http://niemiconsulting.com cutting-edge statistical consulting Thu, 10 Jul 2008 15:22:37 +0000 http://backend.userland.com/rss092 en Yesterday we discussed the negative binomial random variable and we mentioned that it has an infinite number of values consisting of all natural numbers. Another random variable who values consist of all natural numbers and is used more extensively is the Poisson random variable. The Poisson random variable is primarily used ... http://niemiconsulting.com/index.php/2008/07/10/poisson-random-variable/ Continuing our discussion of random variables, we introduce a random variable called the negative binomial. Although it is not one that I use very often, I thought it was a nice transition from the Bernoulli and binomial random variables which have a finite number of values to the random variables ... http://niemiconsulting.com/index.php/2008/07/09/negative-binomial-random-variable/ Continuing our discussion of random variables, we consider the Binomial random variable which is a straight-forward extension of the Bernoulli random variable. The extension is that we perform the same Bernoulli random variable repeatedly. If each trial is independent, i.e. no trial influences any other, than the Binomial random variable ... http://niemiconsulting.com/index.php/2008/07/04/binomial-random-variables/ Yesterday we introduced the idea of a random variable. Today we discuss the easiest random variable to understand, the Bernoulli random variables. Basically any time an outcome has one of two possibilities, it can be modeled as a Bernoulli random variable. Some examples include: will the Minnesota Twins win the next ... http://niemiconsulting.com/index.php/2008/07/02/bernoulli-random-variables/ You probably first remember learning about variables in your elementary algebra class. You probably remember solving for x and y in equations such as Maybe you then moved on to geometry where you were asked to find the degrees of an angle given partial information about other angles and line ... http://niemiconsulting.com/index.php/2008/07/01/random-variables/
