A quantity indicating how sharply a probability distribution function increases and decreases around the distribution's mean.

(Statistics) statistics a measure of the concentration of a distribution around its mean, esp the statistic B2 = m4/m22 where m2 and m4 are respectively the second and fourth moment of the distribution around the mean. In a normal distribution B2 = 3. See also platykurtic, mesokurtic, leptokurtic Compare skewness

If the forecasts were skewed or yielded a flat or platykurtic distribution, there is no consensus.
A platykurtic distribution is often the result of two normal distributions with similar variances but different means, as often occurs with a bimodal distribution.
