  1. A power law is a functional relation of the form f (x)=a xn. f (x) varies as the n th power of x.

    Power law relationships take the form y = c * x^d where c and d are both constants. Taking the log of both sides gives us log(y) = log(c) + d * log(x) which might look familiar. Power laws are linear in terms of log(y) and log(x), which is even clearer if we replace log(c) with a_0 and d with a_1. log(y) = a_0 + a_1 * log(x)

    In statistics, a power law is a functional relationship between two quantities, where a relative change in one quantity results in a relative change in the other quantity proportional to the change raised to a constant exponent: one quantity varies as a power of another. The change is independent of the initial size of those quantities.

    The power-law function indicates that no particular frequency (or time scale in general) dominates the dynamics of the parameter. This feature is called “scale invariance.” It was described at many structural levels: in single-neuron membrane potentials, in local field potentials, and in EEG.

    In a looser sense, a power-law probability distribution is a distribution whose density function (or mass function in the discrete case) has the form, for large values of $${\displaystyle x}$$,

  4. 3 Determine functional form | Data Modeling

    Phenomena that follow power laws are common. You can determine if your data approximately follow a power law by plotting your data using log scales for the x and y axes and then visually checking if the relationship is linear.
