Fisher and logistic discriminant function estimation in the presence of collinearity

Creator:

O'Donnell, Robert P. (Robert Paul)

Abstract:

The relative merits of the Fisher linear discriminant function (Efron, 1975) and logistic regression procedure (Press and Wilson, 1978; McLachlan and Byth, 1979), applied to the two group discrimination problem under conditions of multivariate normality and common covariance, have been debated. In related research, DiPillo (1976, 1977, 1979) has argued...

Dynamic mathematical model of oxygen and carbon dioxide exchange between soil and atmosphere

Creator:

Ou-yang, Ying

Abstract:

Gaseous transport through soil in the presence of soil microorganisms has been investigated. More recently, modeling of gaseous transport in the unsaturated zone has been investigated. However, the problem of mathematical model of oxygen and carbon dioxide transport through soil, as affected by the climatic conditions, the transport of soil...
