Distributional properties of Jaccard's index of similarity

- W. McCormick, N. I. Lyons, K. Hutcheson
- Mathematics
- 1992

The distribution of Jaccard’s coefficient of similarity is shown to be asymptotically normal when the individuals in samples from each population are assumed to follow equiprobable multinomial… Expand

- Mathematics, Medicine
- Journal of theoretical biology
- 21 April 1979

Abstract The covariance between two estimators of Simpson's index of diversity, D , obtained from cumulated samples at two stages of the sampling process is derived. A stopping rule based on a… Expand

Some moments of an estimate of shannon's measure of information

- K. Hutcheson, L. Shenton
- Mathematics
- 1974

An underlying multinomial distribution is assumed and from this the first two moments of an estimate of Shannon's measure of information are derived in closed form. A table of the first two moments… Expand

Distributional Properties of the Number of Moves Index of Diversity

- N. I. Lyons, K. Hutcheson
- Mathematics
- 1 March 1988

The large-sample distribution of the number of moves index of diversity is shown to be approximately normal under the general assumption of asymptotic normality of the species frequencies. Its… Expand

A Significance Test for Morisita’a Index of Dispersion and the Moments when the Population is Negative Binomial and Poisson

- K. Hutcheson, N. I. Lyons
- Mathematics
- 1989

The moments of Morisita’s index of dispersion are derived assuming the observed counts follow negative binomial and Poisson distributions. The moments are expressed as truncated infinite series.… Expand

Distributional properties of simpson's index of diversity

- N. I. Lyons, K. Hutcheson
- Mathematics
- 1979

Closed expressions for the first four moments of Simpson's index of diversity are derived using techniaues suggested by Haldane (1937). As the samole size increases the behavior of the skewness and… Expand

Estimation of Simpson's diversity when counts follow a Poisson distribution

- N. I. Lyons, K. Hutcheson
- Mathematics
- 1 March 1986

Most of the exact distributional properties available for Gini's (1912) index of diversity [more commonly referred to as Simpson's (1949) index] are derived assuming an underlying multinomial… Expand
