Recognizing misclassification bias in research and medical practice

Misclassification Bias in Strategy Research: Analysis and Application

Many issues in strategy and technology management are categorical. Errors in classification of the dependent variable cause systematic bias in regression estimates. In the context of the linear probability model, we characterize the misclassification bias as being proportional to the difference between two measures. One is the “bias” in the explanatory variable, conditional on false negative, m...

Bias Awareness in Research Practice

Bias in Medical/Clinical Research

Learning from clinical experience (whether during formal research or in the course of patient care) is impeded by mainly two processes: bias and chance. Medical research results many times become inconclusive because some bias is detected after the results are available. A dictionary definition of ‘bias’ is ‘a onesided inclination of the mind. In statistics, ‘bias’ is ‘systematic error’ that ca...
