In science:

This is so because forcing the fluctuating variable to become rigorously dichotomous imposes on the system enough coarse graining as to produce randomness.
Fractional Calculus as a Macroscopic Manifestation of Randomness
Eq.(79) is the same as Eq.(40) and the bath variable, now denoted with v , is not dichotomous.
Fractional Calculus as a Macroscopic Manifestation of Randomness
The former property , ψ(t), is the probability density function of so journ times, which, as earlier stressed, has an inverse power law form (see Eq.(1)); the latter, Φξ (t), is the stationary correlation function of the dichotomous variable ξ , playing the role of a velocity with only two possible values, W and −W .
The Levy diffusion as an effect of sporadic randomness
Here we limit ourselves to noticing that this equation is exact under the condition that the velocity variable is dichotomous and the initial distribution is a Dirac delta centered at x = 0.
The Levy diffusion as an effect of sporadic randomness
This is so because Eq.(4) implies the dichotomous nature of the variable ξ .
