Shape of squared normal distributions (solid) and lognormal distributions with the same variance (dashed). For small variances, the distribution is approximately normal (black). For large variances, the distribution saturates at its lower bound (blue). In the intermediate regime, the distribution has a roughly lognormal shape (red).
