While applications of machine learning and data science are becoming commonplace in health research using information derived from Electronic Health Records (EHRs), large biological sample collections (i.e., -omics data), medical imaging data, and sensor data collected using medical devices, applications of large-scale machine learning in the behavioral health care … Continue reading Data Science Challenges in Behavioral Health Care Analysis

Wallenius Naïve Bayes

David Steinberg. One of the simplest methods for two-group classification is naïve Bayes, in which predictors are treated as though they provide independent information. Traditional event models underlying naive Bayes classifiers assume probability distributions that are not appropriate for binary data generated by human behavior. This paper develops a new event model, based on a … Continue reading Wallenius Naïve Bayes

FLAME: A Fast Large-scale Almost Matching Exactly Approach to Causal Inference

David Steinberg. This paper addresses a classical problem in causal inference: matching, where treatment units need to be matched to control units. Some of the main challenges in developing matching methods arise from the tension among (i) inclusion of as many covariates as possible in defining the matched groups, (ii) having matched groups with enough … Continue reading FLAME: A Fast Large-scale Almost Matching Exactly Approach to Causal Inference

Mind the Gap: Accounting for Measurement Error and Misclassification in Variables Generated via Data Mining

David Steinberg. Yang et al. consider the application of predictive data mining techniques in Information Systems research. Their focus is on the impact of data errors and misclassification on the subsequent data analysis by econometric models. Typically, data mining methods are first used to generate new variables (e.g., text sentiment), which are added into subsequent … Continue reading Mind the Gap: Accounting for Measurement Error and Misclassification in Variables Generated via Data Mining
