4 Absorbing Markov Chains - SSCC - Home

4 Absorbing Markov Chains So far, we have focused on regular Markov chains for which the transition matrix P is primitive. Because primitivity requires P(i,i) < 1 for every state i, regular chains never get “stuck” in a particular state. However, other Markov chains may have one

Review of Probability Theory - Stanford University

For some continuous random variables, the cumulative distribution function F X(x) is differentiable everywhere. In these cases, we define the Probability Density Function or PDF as the derivative of the CDF, i.e., f X(x) , dF X(x) dx: (2) Note here, that the PDF for a continuous random variable may not always exist (i.e., if F X(x) is not

Reading 5b: Continuous Random Variables

Continuous Random Variables and Probability Density Func­ tions. A continuous random variable takes a range of values, which may be finite or infinite in extent. Here are a few examples of ranges: [0, 1], [0, ∞), (−∞, ∞), [a, b]. Definition: A random variable X is continuous if there is a function f(x) such that for any c ≤ d we ...
