Compositional discriminant function analysis of bank stability on the basis of hydraulic geometry had a success rate of 88%, making routinely archived measurements of stream width, cross-sectional area, mean velocity, and discharge a readily
Derivation of the chalk superficial deposits of the North Downs, England : an application of discriminantanalysis
Cenozoic ; Chalk ; Discriminantanalysis ; England ; Grain size distribution ; Heavy minerals ; Model ; Sedimentology ; Surface deposits ; United Kingdom
This paper briefly surveys the role of superficial sediments in landscape models of the last 50 years and the methods used to characterize them. Stepwise discriminantanalysis was then used on particle size and heavy mineral data from 276 sediment
Discriminant function analysis of glass chemistry of New Zealand and North American tephra deposits
function analysis (DFA) to assess the relative discriminating power of the different elements in volcanic glasses from several tectonovolcanic provinces.
Major, trace, and rare earth element analyses of volcanic glass are used separately or in combination for correlating Quaternary tephras, often by graphical or simple comparative methods. The AA. have taken a statistical approach using discriminant
Test sous forme d'analyse canonique permettant de vérifier qu'il existe bien certaines formes de discrimination dans la politique de prêts des deux banques commerciales, pourtant interdites par la loi. Analyse des caractéristiques des emprunteurs et
Ein Verfahren zur Aufstellung statistischer Prognosealgorithmen als Einheit von Cluster-, Diskriminanz- und Regressionsanalyse (A method for the development of statistical forecasting algorithms including cluster, discriminance and regression
analysis)
The method presented by the author is used to develop a large number of predictors within a system of multiple regression equations with a series of classifications. The method includes an ideal classification, a screening discriminanceanalysis
and a stepwise, multiple, regression analysis based upon the cross-validation technique. - (IH)

The classic channel slope-discharge relationship proposed by Leopold and Wolman (1957) for channel pattern discrimination has been tested by a large database including 4 types of rivers : gravel-bed meandering rivers, gravel-bed braided rivers, sand
-bed meandering rivers and sand-bed braided rivers. The result shows that this relationship cannot discriminate channel patterns well when both gravel- and sand-bed rivers are considered. The channel width-bankfull discharge relationship suggested by XU
(1996) for discrimination of channel patterns of sand-bed rivers in China, is also tested in this study by the same database. Discussion of the results.
Comparison of hydraulic geometry between sand- and gravel-bed rivers in relation to channel pattern discrimination

for discrimination of meandering and braided channel patterns have been established. To predict the development of channel patterns under different natural conditions, the pattern discriminator should be searched on the basis of independent or at least semi
-independent variables. The relationship between stream power and bed material grain size shows a better result than the discriminator using the slope-discharge relationship.
Application of the QDa-Md method of environmental discrimination to particle size analyses of fine sediments by pipette and sedigraph methods: a comparative study

analyses. Their database includes a sample population of 68 cases. Results of discriminantanalysis based on fan and basin variables are much more significant than those based on fan variables only.
In order to understand if and to what extent fan types and their morphology are dependent on the physical environment, including characteristics and processes of the depositional site and drainage basin, the AA. performed a series of discriminant
included in a discriminant function in order to define landslide susceptibility classes. To this purpose the AA. have used a set of data that have been collected in the field. The validity of the discriminant function for landslide susceptibility assessment
The discrimination between alternative and interacting causes in geographical research in European progress in spatial analysis.
Bien souvent, les géographes distinguent mal le problème de discrimination de causes alternatives et mutuellement exclusives de l'analyse des causes dont les interactions concourent à produire un seul effet. Cela entraîne immanquablement une
A multivariate analysis of the determinants of urban quality of life in the world's largest metropolitan areas
Index ; Large city ; Multivariate analysis ; Quality of life ; Urban life ; Well-being ; World
The urban living standard index of the Population Crisis Committee, based on 10 indicators of urban quality of life for the 98 largest cities of the world, is used here to create three groups of cities. The discriminantanalysis technique is applied
for identifying the measures that contribute most in their formation. Food cost is the most influential discriminator and the others are living space and housing standard.
