Chapter 6 - Random Processes

In general, a complete statistical description of a random process requires knowledge of all order distribution functions. Stationary Random Process A process X(t) is said to be stationary if its statistical properties do not change with time. More precisely, process X(t) is stationary if

random sampling scheme was employed to select random sampling positions within each identified property. Additionally, during this refined analysis two extra properties were added to the sampling design (one nursery located within 2 Km of the factory and one previously overlooked park), along with 12 additional sampling locations on the factory

In addition to its interpretation as a relative frequency as used in classical statistics, the Bayesian approach using subjective probability is discussed as well.
