A new technique for evaluating land use regression models and their impact on health effect estimates
Epidemiology
BACKGROUND: Leave-one-out cross-validation that fails to account for variable selection does not properly reflect prediction accuracy when the number of training sites is small. The impact on health effect estimates has rarely been studied. OBJECTIVE...

Internal validation inferences of significant genomic features in genome-wide screening
Comput Stat Data Anal
Although validation of classification and prediction models has been a long-standing topic in Statistics and computer learning, the concept of statistical validation in genome-wide screening studies has been vague. Internal validation generally refer...

Extensions of the External Validation for Checking Learned Model Interpretability and Generalizability
Patterns (N Y)
We discuss the validation of machine learning models, which is standard practice in determining model efficacy and generalizability. We argue that internal validation approaches, such as cross-validation and bootstrap, cannot guarantee the quality of...

An empirical assessment of validation practices for molecular classifiers
Brief Bioinform
Proposed molecular classifiers may be overfit to idiosyncrasies of noisy genomic and proteomic data. Cross-validation methods are often used to obtain estimates of classification accuracy, but both simulations and case studies suggest that, when inap...
