Scale Mixture of Normal Distributions Recent studies of stock returns tend to use scale mixture or finite mixture of normal distributions. , rt ~ N(μ, σ2)]. , σ−2 follows a gamma distribution). An example of finite mixture of normal distributions is where X is a Bernoulli random variable such that P(X = 1) = α and P(X = 0) = 1 − α with 0 < α < 1, is small, and is relatively large. 05, the finite mixture says that 95% of the returns follow and 5% follow . The large value of enables the mixture to put more mass at the tails of its distribution.
