The fidelity of dynamic signaling by noisy biomolecular networks: Supplementary Information

Conditional expectations are not commonly used outside of probability and statistics. We present here a short introduction and list of their properties. For a random variable Z and a random vector X, the conditional expectation E[Z|X] is itself a random variable because it is a function of the random variables in X. For continuous random variables, E[Z|X] is defined as E[Z|X = x] = ∫ dz z p(z|x) (16)
