A Polaris logistics model [PDF]

open access: possibleNaval Research Logistics Quarterly, 1964
AbstractThis paper presents a basic loss minimization model which has been applied in varying contexts for Polaris logistics problems. Definitive results are obtained in a general framework which extends the classic newsboy problem in two principal directions. First, probability distributions for demand are unrestricted. Second, a general framework for

PREDICTIVE DIAGNOSTICS FOR LOGISTIC MODELS

Statistics in Medicine, 1996
Novel methodology is implemented to assess the predictive power of covariate information associated with sequential binary events. Logistic models are first fitted on the basis of a subset of the observations and then evaluated sequentially on the rest.

Logistics System Modelling

International Journal of Physical Distribution & Materials Management, 1978
In a logistics system the number of possible applications of qualitative and quantitative modelling efforts is practically infinite. The situations or problems which can be analysed range from micro operations (e.g., analysing alternative order picking systems) to macro planning issues (e.g., determining the number and location of warehouses to be ...

The Logistic Regression Model

2019
Among the statistical preliminaries of education in the theory of gnostic clinical research, centrally important are, first, the precursors of logistic regression, culminating in the emergence of the General Linear Model; and then the generalization of this to the Generalized Linear Model, with logistic regression model a special case of this.

A Generalized Logistic Tobit Model

Journal of quantitative economics, 1991
This paper proposes the use of a generalisation of the Logistic distribution, the Burr Type II distribution, as the error structure in a Type I (Standard) Tobit model. The use of the Burr II is motivated through both an heterogeneity argument and by noticing the need for potentially non-symmetric distributions in Tobit models.

Logistics composite modeling

1997
A supply chain is the collection of all components and functions associated with the creation and ultimate delivery of a product or service. Figure 2.1 illustrates an example product supply chain.

Multivariate logistic models

Biometrika, 2006
SUMMARY The multivariate logistic transform is a reparameterisation of cell probabilities in terms of marginal logistic contrasts. It is known that an arbitrary set of logistic contrasts may not correspond to a valid joint distribution. In this paper we present an efficient algorithm for detecting whether or not the inverse transform exists, and for ...

Logistic Growth Models [PDF]

open access: possible, 2003
Differential equation models, whether ordinary, delay, partial or stochastic, imply a continuous overlap of generations. Many species leave no overlap between successive generations and so population growth is in discrete steps. For primitive organisms, these discrete steps can be quite short, and hence a continuous (in time) model may be a reasonable ...

A program for logistic prediction modelling

Computer Programs in Biomedicine, 1985
A computer program has been developed that can be used for analysing a binary outcome variable and a set of regressors of type interval with a logistic (i.e. nonlinear) model.
