pyarts3.arts.random.lognormal_distribution

random.lognormal_distribution(N: int = 1, mean: float = 0.0, stddev: float = 1.0) → pyarts3.arts.Vector

Generate random numbers following a lognormal distribution

Wraps std::lognormal_distribution from the C++ standard library.

import matplotlib.pyplot as plt

Parameters:

• N (int) – Number of random numbers to generate. Default is 1.

• mean (float) – Mean of the underlying normal distribution. Default is 0.0.

• stddev (float) – Standard deviation of the underlying normal distribution. Default is 1.0.

Returns:

The distribution

Return type:

Vector
