Definition of leptokurtic in English:

leptokurtic

adjective ˌlɛptə(ʊ)ˈkəːtɪk

Statistics

(of a frequency distribution or its graphical representation) having greater kurtosis than the normal distribution; more concentrated about the mean.
〔统计〕尖峰态的（频数分布或其图示中峰态大于正常分布时）。比较PLATYKURTIC , MESOKURTIC
Compare with platykurtic, mesokurtic
Example sentencesExamples
- The evidence from House Finches suggests that vagrants are simply the individuals that make up the long tails of leptokurtic frequency distributions typical of data on distances moved by animals.
- The fitness distribution of the MA lines is leptokurtic and skewed to the left.
- However, all of the fitness and morphological traits they reviewed had distributions of mutant effects more leptokurtic than a normal distribution.
- Bluehead chub, creek chub, and redbreast sunfish movement distributions were significantly leptokurtic.
- Frequency distributions of distances dispersed by animals are most always leptokurtic.

Derivatives

leptokurtosis

nounˌlɛptə(ʊ)kəˈtəʊsɪs

Statistics

In previous samples, these characters have been shown to exhibit very little directional asymmetry and slight leptokurtosis, as expected of FA.
Example sentencesExamples
- In contrast, creek chubs showed little evidence of persistent upstream bias, and their leptokurtosis, while evident in the first three months, showed a decreasing trend with time, vanishing by the fourth month.
- The spatial spread of the most abundant species, bluehead chubs, over a four-month period was characterized by upstream bias, diffusion-like spread, and persistent leptokurtosis.
- The population heterogeneity model matched the leptokurtosis, variance, and overall distribution of the movement data.
- Since leptokurtosis is a common pattern in movement data, a model of movement with population heterogeneity, such as that described here, may prove useful whenever spatial structure is implicated.

Origin

Early 20th century: from lepto- 'narrow' + Greek kurtos 'bulging' + -ic.
