1939 A. E. Treloar Elements Statist. Reasoning ii. 34 Positive (or lepto-) kurtosis, mesokurtosis (that of the ‘law of error’ or normal curve), and negative (or platy-) kurtosis mean simply that the clustering at the center is respectively greater than, equal to, or less than that of the normal curve.
1979 Nature 25 Jan. 297/1 Platykurtosis is not sufficient to demonstrate bimodality, but bimodal distributions are platykurtic.
2002 Jrnl. Private Equity (Nexis) 22 June 6 Kurtosis is measured relative to a normal, bell-shaped distribution... A negative value indicates a distribution with ‘thinner’ than normal tails (platykurtosis)... A distribution of returns with thin tails indicates less exposure to outlier events.
