Binary evaluation
The evaluation of binary classifiers compares two methods of assigning a binary attribute, one of which is usually a standard method and the other is being investigated. There are many metrics that can be used to measure the performance of a classifier or predictor; different fields have different … See more Given a data set, a classification (the output of a classifier on that set) gives two numbers: the number of positives and the number of negatives, which add up to the total size of the set. To evaluate a classifier, one … See more The fundamental prevalence-independent statistics are sensitivity and specificity. Sensitivity or True Positive Rate (TPR), also known as recall, is the proportion of people that tested positive … See more Precision and recall can be interpreted as (estimated) conditional probabilities: Precision is given by $${\displaystyle P(C=P {\hat {C}}=P)}$$ while recall is given by $${\displaystyle P({\hat {C}}=P C=P)}$$, where $${\displaystyle {\hat {C}}}$$ is the predicted class and See more In addition to sensitivity and specificity, the performance of a binary classification test can be measured with positive predictive value (PPV), also known as precision, and negative predictive value See more In addition to the paired metrics, there are also single metrics that give a single number to evaluate the test. Perhaps the simplest statistic is accuracy or fraction correct … See more • Population impact measures • Attributable risk • Attributable risk percent • Scoring rule (for probability predictions) See more WebThese lecture slides offer practical steps to implement DID approach with a binary outcome. The linear probability model is the easiest to implement but have limitations for prediction. Logistic models require an additional step …
