Quantitative Structure-Activity Relationships: Linear Regression Modelling and Validation Strategies by Example QSARs-LRM Modelling and Validation Strategies by Example

Quantitative structure-activity relationships are mathematical models constructed based on the hypothesis that structure of chemical compounds is related to their biological activity. A linear regression model is often used to estimate and predict the nature of the relationships between a measured activity and some measure or calculated descriptors. Linear regression helps to answer main three ...

Sinusoidal Cox Regression—A Rare Cancer Example

Evidence of an association between survival time and date of birth would suggest an etiologic role for a seasonally variable environmental exposure occurring within a narrow perinatal time period. Risk factors that may exhibit seasonal epidemicity include diet, infectious agents, allergens, and antihistamine use. Typically data has been analyzed by simply categorizing births into months or seas...

Robust Redundancy Analysis by Alternating Regression

Given two groups of variables redundancy analysis searches for linear combinations of variables in one group that maximizes the variance of the other group that is explained by the linear combination. The method is important as an alternative to canonical correlation analysis, and can be seen as an alternative to multivariate regression when there are collinearity problems in the dependent set ...

Clustering Stream Data by Regression Analysis

In data clustering, many approaches have been proposed such as K-means method and hierarchical method. One of the problems is that the results depend heavily on initial values and criterion to combine clusters. In this investigation, we propose a new method to cluster stream data while avoiding this deficiency. Here we assume there exists aspects of local regression in data. Then we develop our...
