Specify a normal distribution of the form exp(normal(mu, sigma))

Specify a normal distribution of the form exp(normal(mu, sigma)).

The logarithm of the return value is normally distributed. When optimizing, this variable is constrained to be positive.

lognormal(mu, sigma)

Arguments

mu	A double of the mean of the normal distribution.
sigma	A double of the standard deviation of the normal distribution.

Value

A list of the stochastic expression.
