OLS Regression?, Auto-Regression?, Dynamic Regression?: A Practical Modeling Example in Financial Industry

Regression models are commonly applied when it comes to planning or forecasting. Financial data - due to their historical features of the trend component, cyclical component, and irregular component - might not fit well with traditional regression models. In such cases, an autoregression model or a dynamic regression model will...

Nonlinear Least Squares Regression - CurveFitter 4.5 (Windows)

CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting. Curvefitter...

Easy-Fit Express 1.0 (Windows)

The software system solves constrained nonlinear parameter estimation problems. Synonyms are data fitting, nonlinear regression, parameter identification, curve and surface fitting. The numerical methods are based on highly efficient Gauss-Newton-SQP algorithms. Model functions are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime.

SUSE Linux Enterprise Desktop 11: Lots of Tech but Short on Polish

At first glance, Novell's SUSE Linux Enterprise Desktop 11 (SLED 11) is virtually indistinguishable from the company's Free/Open Source and community supported Linux distribution, openSUSE 11.1. But does SLED 11 have the extra polish and the value add to justify its position as Novell's premier enterprise...

Generalizations of Generalized Additive Model (GAM): A Case of Credit Risk Modeling

Famous for its easy implementation, Logistic Regression has been the primary model in credit scoring. Albeit attractively simple, it is criticized for failing to capture nonlinearity and nonmonotonicity and therefore possibly not leads to satisfactory results. Introduced by Hastie and Tibshirani, Generalized Additive Model GAM provides the ability to detect...

The Problem of Regression Assumptions and the Use of Predictive Modeling

Predictive modeling includes regression, both logistic and linear, depending upon the type of outcome variable. However, as the datasets are generally too large for a p-value to have meaning, predictive modeling uses other measures of model fit. Generally, too, there are enough observations so that the data can be partitioned...

A Class of Predictive Models for Multi-Level Risks

In the financial service industry, discriminant analysis and its variants based upon binary outcome, such as logistic regression or neural networks, are largely used to develop predictive models. However, the two-state assumption of such models over-simplifies customers' behavioral outcomes and ignores the existence of multi-level risk. In many situations, the...
