Definition that contains random variable
- mode the most frequent value of a random variable
- expectation the sum of the values of a random variable divided by the number of values
- variance the second moment around the mean; the expected value of the square of the deviations of a random variable from its mean value
- stochastic process a statistical process involving a number of random variables depending on a variable parameter (which is usually time)
- modal value the most frequent value of a random variable
- co-vary vary in the same time period (of two random variables)
- second moment the expected value of the square of the deviations of a random variable from the point of origin
- expected value the sum of the values of a random variable divided by the number of values
- stationary stochastic process a stochastic process in which the distribution of the random variables is the same for any value of the variable parameter
- stochastic being or having a random variable
