    Identifying regional seismic relationships by cross-correlation (1995)
    Springer
    Pure and applied geophysics 144 (1995), S. 301-306 
    Details
    ISSN: 1420-9136
    Keywords: Cross-correlogram ; hypothesis test ; serial independence
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract The identification of relationships between seismicity in different regions is commonly based on establishing the statistical significance of the largest absolute value in the cross-correlogram between time series of seismicity. The assessment of significance typically ignores the selection of the largest absolute value in the cross-correlogram and consequently exaggerates significance. In this note, a simple method for correcting the significance level for selection is presented. The method is valid as long as the two series are each serially independent. An example concerning seismicity in Mexico and Kamchatka is presented. In this case, correcting for selection has a dramatic effect.

    Testing for density dependence (1990)
    Springer
    Oecologia 83 (1990), S. 47-49 
    Details
    ISSN: 1432-1939
    Keywords: Density dependence ; Random walk ; Autoregressive process
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The robustness and sensitivity of a test for density dependence in an animal population against departures from the assumed null and alternative model is assessed via simulation. The test is shown to be nonrobust and insensitive to departures from the assumed models.

    On the detection of greenhouse warming (1989)
    Springer
    Climatic change 15 (1989), S. 449-453 
    Details
    ISSN: 1573-1480
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract Two facts that have been cited as evidence of the onset of greenhouse warming are the extent to which the most recent value in a global temperature series is unusually warm and the observation that the four warmest years on record occurred in the 1980's. We examine these results in more detail, and we address the question as to whether these facts constitute evidence in favor of the detection of greenhouse warming. We conclude that they do not support detection unless we are prepared to attribute all warming in the data to the greenhouse effect.

    Inferring extinction in a declining population (1993)
    Springer
    Journal of mathematical biology 32 (1993), S. 79-82 
    Details
    ISSN: 1432-1416
    Keywords: Sighting data ; Non-stationary Poisson process ; Black-footed ferret
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Mathematics
    Notes: Abstract This note describes a test for extinction in a declining population based on a record of sightings. The test assumes that, prior to extinction, the sightings follow a Poisson process with decreasing rate function. An application to a sighting record of the black-footed ferret is presented.

    Estimating the size of the source population from a matched sample of parts (1996)
    Springer
    Mathematical geology 28 (1996), S. 783-789 
    Details
    ISSN: 1573-8868
    Keywords: disarticulation ; maximum likelihood estimation ; taphonomy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Mathematics
    Notes: Abstract This paper discusses the problem of estimating the size of a source population from a sample of matched, disaritculated body parts. Maximum likelihood estimation and the construction of a confidence interval are described. This problem is connected to the ecological problem of estimating the number of spectes in a sampled community.
