Preface 1. Regional frequency analysis 2. L-moments 3. Screening the data 4. Identification of homogeneous regions 5. Choice of a frequency distribution 6. Estimation of the frequency distribution 7.…
Some statistics useful in regional frequency analysis
- J. Hosking, J. R. Wallis
- Sociology
- 1 February 1993
Regional frequency analysis uses data from a number of measuring sites. A “region” is a group of sites each of which is assumed to have data drawn from the same frequency distribution. The analysis…
Estimation of the generalized extreme-value distribution by the method of probability-weighted moments
- J. Hosking, J. R. Wallis, E. Wood
- Mathematics
- 1 August 1985
We use the method of probability-weighted moments to derive estimators of the parameters and quantiles of the generalized extreme-value distribution. We investigate the properties of these estimators…
Some ecological consequences of a computer model of forest growth
- D. Botkin, J. Janak, J. R. Wallis
- Environmental Science
- 24 March 1972
A computer simulation of forest growth is now developed that successfully reproduces the population dynamics of the trees in a mixed-species forest of north-east North America.
Probability Weighted Moments: Definition and Relation to Parameters of Several Distributions Expressable in Inverse Form
- J. Greenwood, J. M. Landwehr, N. Matalas, J. R. Wallis
- Mathematics
- 1 October 1979
Distributions whose inverse forms are explicitly defined, such as Tukey's lambda, may present problems in deriving their parameters by more conventional means. Probability weighted moments are…
Regional frequency analysis
- J. Hosking, J. R. Wallis
- Geology
- 1997
Introduction Frequency analysis is the estimation of how often a specified event will occur. Estimation of the frequency of extreme events is often of particular importance. Because there are…
Some long‐run properties of geophysical records
- B. Mandelbrot, J. R. Wallis
- Geology
- 1 April 1969
By preparing this book Chris Barton and Paul La Pointe have earned the gratitude of all geologists and students of fractals. I continue to belong to this second group, and Chris and Paul clearly have…
Robustness of the rescaled range R/S in the measurement of noncyclic long run statistical dependence
- B. Mandelbrot, J. R. Wallis
- Mathematics
- 1 October 1969
The rescaled range R(t, s) / S(t, s) is shown by extensive computer simulation to be a very robust statistic for testing the presence of noncyclic long run statistical dependence in records and, in…
Noah, Joseph, and Operational Hydrology
- B. Mandelbrot, J. R. Wallis
- Environmental Science
- 1 October 1968
By ‘Noah Effect’ we designate the observation that extreme precipitation can be very extreme indeed, and by ‘Joseph Effect’ the finding that a long period of unusual (high or low) precipitation can…
Hydro-Climatological Trends in the Continental United States, 1948-88
- D. Lettenmaier, E. Wood, J. R. Wallis
- Environmental Science
- 1 April 1994
Abstract Spatial patterns in trends of four monthly variables: average temperature, precipitation, streamflow, and average of the daily temperature range were examined for the continental United…
