A large number of collective oscillations which result from simultaneous, ordered motions of all particles in a system or of particle subsystems [1–3] are one of the most general properties of a turbulent plasma. The plasma parameters resulting from the superposition of those oscillations, e.g., the electric and magnetic fields, the plasma density, the temperature, the spectral characteristics, etc., are random functions of time. Under these conditions, multidimensional probability-distribution functions of these quantities can provide full information on a turbulent plasma. The measurement of these functions encounters great experimental and computational difficulties. Thus, in the majority of cases, fluctuations are disregarded and only average values of the plasma parameters are measured. Knowledge about the average values alone can provide only a rough idea of the processes occurring in the plasma because the fluctuations include information on collective plasma oscillations.
