Summary
This chapter discusses some basic concepts quantifying the characteristics of functions with random fluctuations. Deterministic functions are discussed first in order to introduce functions with randomness and ways to quantify them. The concepts of phase space, ensemble mean, ergodic process, moments, covariance functions, and correlation functions are discussed briefly.
