(of a frequency distribution or its graphical representation) having less kurtosis than the normal distribution.
- ‘For instance, regenerative recruitment of adjacent release units might explain the platykurtic sub-population of sparks under some experimental conditions.’
- ‘All distributions of signed asymmetry tended to be lepto - rather than platykurtic, so antisymmetry could definitely be excluded.’
- ‘The best-fitting models therefore imply platykurtic distributions of mutational effects, although it is not possible to discriminate between these models and models involving bimodal distributions of mutation effects.’
Early 20th century: from platy- broad, flat + Greek kurtos bulging + -ic.
