It is also used to describe a restricted occupancy distribution in “ball and urn” investigations [2]. Historical Notes on the Romanovsky Distribution Haight [3] lists Romanovsky’s distribution in the index yet points to […]

  • Tine Distribution

    < Back to Probability Distribution List The Tine distribution (sometimes called symmetric triangular distribution) made an entry in the Index to the Distributions of Mathematical Statistics [1] as: The Annals of Mathematical Statistics [2] contains an expanded definition: Rinne [3] defines Tine’s distribution as the distribution of two independent and identically distributed uniform variables (i.e., […]

  • Gram-Charlier Distribution

    < Back to Probability Distribution List The Gram-Charlier distribution is a way to explicitly model departure from normality by using a series expansion around a normal distribution. It is more flexible than a normal distribution because it directly introduces a distribution’s kurtosis and skew as unknown parameters. The One practical application of the Gram-Charlier distribution […]
