Constructor Detail

LogNormalDistribution

public LogNormalDistribution(Expression mean,
                             Expression variance)
                      throws ExceptionHugin

Constructs a new LogNormalDistribution. If X is a random variable with a log-normal distribution, then log(X) has a normal distribution.

Parameters:

mean - mean of log(X)

variance - variance of log(X) [note: not standard deviation]

LogNormalDistribution

public LogNormalDistribution(Expression mean,
                             Expression variance,
                             Expression location)
                      throws ExceptionHugin

Constructs a new LogNormalDistribution. If X is a random variable with a log-normal distribution, then log(X) has a normal distribution.

Parameters:

mean - mean of log(X)

variance - variance of log(X) [note: not standard deviation]

location - minimum value of X [i.e., log(X-location) has a normal distribution]
