at small distance lags, several levels of spatial variability of the textural fractions ranging from within-a-field to polder scale were identified. This structure was best represented by nested semivariograms.

Specification tests for nested logit models

This paper tests the hypothesis that termites contribute to a stable microgranular, i.e., finely aggregated, soil structure. To this end the AA. examined the microaggregates of a termite mound with an active nest but old enough to show soil profile
VAN DEN ANCKER, J.A.M.

The levels of variance associated with measuring the infiltration process and modelling it by means of a regression model are compared to see which approach yields the best results in terms of effort and accuracy. A nested sampling scheme has been

Application on nested sampling technique to determine the scale of variation in soil physical and chemical properties
The objective of this investigation was to determine optimal sampling scheme and distances, which allow to calculate the most informative semi-variogram for all variables of interest by only one sampling event. Nested sampling and nested analysis

to a detailed inventory of phanerogamic plants| nesting birds were recorded by square km. The floristic diversity amounts to 425 species| 73 bird species have been observed for a total area of 1627 ha. The data were weighed according to both a local
and a regional rarity scale and the results ranked into five classes of value. Combining the ornithological and botanical values by means of the VAN DER MAAREL formula yields a global ecological assessment for each of the 353 ecotopes present in the land

Energy-saving housing improvements in Canada (1979-82) : a nested logit analysis
A nested multinomial logit model is estimated, which predicts the likelihood that individual households will carry out different retrofitting measures. The model indicates that the government programs succeed in reducing socioeconomic barriers

Centres, peripheries, and party systems : nested secession processes in Great Britain and Ireland
The article explores the capacity of a model to explain party divisions in three nested contexts : the pre-1922 UK (problems with Celtic peripheries), independent Ireland (unique party system) and Northern Ireland. The models casts valuable light

Alternative nested logit model structures and the special case of partial degeneracy

Combining nested and linear sampling for determining the scale and form of spatial variation of regionalized variables

Non-nested tests on the weight structure in spatial autoregressive models: some Monte Carlo results

Stick-nest rat middens as sources of paleoecological data in Australian deserts
In this paper the content of several well-preserved stick-nest rat middens is examined to determine their potential for paleoecological reconstruction. In particular, the research was structured to examine whether pollen records varied among midden
