Kernel matching: same as radius matching, except control observations are weighted as a function of the distance between the treatment observation's propesnity score and control match propensity score. One example is the Epanechnikov kernel. Radius matching is a special case where a uniform kernel is used.
Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an ... Propensity score matching, ...
Propensity scores for sample inclusion are estimated using a logistic regression. The predictors in the propensity score model include the demographics described above (age, race, gender, and education) plus marital status, number of children, household ownership, frequency of internet use, interest in politics, and past voting behavior.
The propensity theory of probability is a probability interpretation in which the probability is thought of as a physical propensity, disposition, or tendency of a given type of situation to yield an outcome of a certain kind, or to yield a long-run relative frequency of such an outcome.
Paul R. Rosenbaum is the Robert G. Putzel Professor Emeritus in the Department of Statistics and Data Science at Wharton School of the University of Pennsylvania, where he worked from 1986 through 2021.
Other tests assess specific capabilities, such as coding, or evaluate models' capacity and propensity for potentially dangerous behaviors like persuasion, deception, and large-scale biological ...
Probability matching is a decision strategy in which predictions of class membership are proportional to the class base rates.Thus, if in the training set positive examples are observed 60% of the time, and negative examples are observed 40% of the time, then the observer using a probability-matching strategy will predict (for unlabeled examples) a class label of "positive" on 60% of instances ...
