A Regression-Based Analytic Model for Dynamic Resource Provisioning of Multi-Tier Applications: The multi-tier implementation has become the industry standard for developing scalable client-server enterprise applications. Since these applications are performance sensitive, effective models for dynamic resource provisioning and for delivering quality of service to these applications become critical. Workloads in such environments are characterized by client sessions of interdependent requests with...; Tags: client-server, implementation, regression, provisioning, ieee, servers, hardware; White papers 2007-06-16

Using SAS Proc NLMIXED for Robust Regression: This paper shows how the NLMIXED procedure can be used to fit linear models (simple linear regression, multiple linear regression, analysis of variance and analysis of covariance) when data are not normally distributed or contaminated with potential outliers. This is accomplished using PROC NLMIXED's capability of fitting user defined distributions...; Tags: regression, sas institute; White papers 2007-05-14
Variable Screening for Multinomial Logistic Regression on Very Large Data Sets as Applied to Direct Response Modeling: Beginning with version 8.2 SAS supports multinomial logistic regression as part of PROC LOGISTIC. As a direct response modeling provider, the authors have found that multinomial logistic regression models often provides with the best solutions. However, using multinomial logistic regression presents some challenges. Programmers are often faced with very large...; Tags: regression, sas institute, modeling, research & development, business operations; White papers 2007-05-14
Regression Splines With Longitudinal DATA: To account for the longitudinal nature of the data, a mixed model analysis implemented using SAS PROC MIXED is commonly used. It is typical to make comparisons between dose or treatment groups, possibly controlling for demographic variables. When the dose response curve is non-linear, it can be difficult to find...; Tags: regression, sas institute; White papers 2007-05-14
Regression Testing: Testers are under an obligation to carry out regression testing. This is not an obligation to be taken lightly!
