Random element is absolutely continuous, its distribution can be described by a probability density function, which assigns probabilities to intervals; in particular, each individual point must necessarily have probability zero for an absolutely continuous random variable. Not all continuous random variables are absolutely continuous, for example a mixture distribution. Such random variables cannot be described by a probability density or a probability mass function. A random vector is a column vector formula_24 (or its transpose, which is a row vector) whose components are scalar-valued random variables on the same probability space formula_1, where formula_26 is the sample space, formula_5 is the sigma-algebra
