Should linking replace regression when mapping from profile-based measures to preference-based measures?

چکیده
BACKGROUND Profile instruments are frequently used to assess health-related quality of life and other patient-reported outcomes. However, preference-based measures are required for health-economic cost-utility evaluations. RESULTS Although regression-based approaches are commonly used to map from profile measures to preference measures, we show that this results in biased estimates because of regression to the mean. CONCLUSIONS Linking (scale-aligning) is proposed as an alternative.

The Effect of Transitive Closure on the Calibration of Logistic Regression for Entity Resolution
This paper describes a series of experiments in using logistic regression machine learning as a method for entity resolution. From these experiments the authors concluded that when a supervised ML algorithm is trained to classify a pair of entity references as linked or not linked pair, the evaluation of the model’s performance should take into account the transitive closure of its pairwise lin...

AIMS The aim of this study was to develop two diabetes-specific preference-based measures [the Diabetes Health Profile-3 Dimension (DHP-3D) and the Diabetes Health Profile-5 Dimension (DHP-5D)] for use in the calculation of Quality Adjusted Life Years, a key outcome in economic evaluation. These measures were based on the non-preference-based instrument the Diabetes Health Profile. METHODS Fo...

PURPOSE To estimate a utility-based glaucoma health outcome measure, known as the Glaucoma Utility Index. METHODS Based on focus group studies, involving people with glaucoma, existing profile measures relevant to glaucoma were modified and a six-dimensional profile instrument was developed. Dimensions were: central and near vision; lighting and glare; mobility; activities of daily living; ey...

In this paper, we aim to overcome three major shortcomings of the FDH (Free Disposal Hull) directional distance function through developing two new, named Linear and Fractional CDFDH, complete FDH measures of efficiency. To accomplish this, we integrate the concepts of similarity and FDH directional distance function. We prove that the proposed measures are translation invariant and unit invari...
متن کاملUsing Regression based Control Limits and Probability Mixture Models for Monitoring Customer Behavior
In order to achieve the maximum flexibility in adaptation to ever changing customer’s expectations in customer relationship management, appropriate measures of customer behavior should be continually monitored. To this end, control charts adjusted for buyer’s/visitor’s prior intention to repurchase or visit again are suitable means taking into account the heterogeneity across customers. In the ...
