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.
