Regression Outliers

Regression Outliers An outlier is an extreme observation. Typically points further than, say, three or four standard  deviations from the mean are considered as “outliers”. How to detect outliers and see more:  Regression Outliers

Pseudo-R2 Measures for Common Limited Dependent Variable Models

Pseudo-R2 Measures for Common Limited Dependent Variable Models  This paper reviews some of the many R2-type measures (or Pseudo- R2's) that have been proposed for estimated limited dependent variable models. A limited dependent variable model is a model where the observed dependent variable is constrained, such as in the binary model where it must be either zero or one.

Probability History

History of Probability What is Probability? In essence:   Mathematical modeling of random events and phenomena. It is fundamentally different from modeling deterministic events and functions, which constitutes the traditional study of Mathematics.   However, the study of probability uses concepts and notions taken straight from Mathematics; in fact Measure Theory and Potential theory are expressions of abstract mathematics generalizing  the theory of Probability.   See more:  History of Probability
