such as accuracy, the overall correctness of the model’s predictions, and recall, the ratio of correctly predicted positive observations. Also consider how the model’s predictions are affecting business outcomes on the ground—is it generating value, whether in increased sales of blouses or better...

Predictive analytics is the use of data, statistical algorithms and machine learning techniques to identify the likelihood of future outcomes based on historical data. The goal is to go beyond knowing what has happened to providing a best assessment of what will happen in the future. History ...
In this logistic regression equation, logit(pi) is the dependent or response variable and x is the independent variable. The beta parameter, or coefficient, in this model is commonly estimated via maximum likelihood estimation (MLE). This method tests different values of beta through multiple itera...
Statistics: Are the estimates produced by probit and logit with the vce(cluster clustvar) option true maximum likelihood estimates? (Updated 26 June 2017) Statistics: How can I use Stata to calculate power by simulation? (Updated 26 June 2017) Statistics: Can Stata estimate a Rasch model?
Box 8: The likelihood of under the alternative is , or (one minus the false negative rate). Box 9: The likelihood ratio is . Box 10: The product of Box 5 and Box 9 is approximately . Box 11: The posterior probability is approximately . Box 12: The posterior probability is appr...

An example of logistic regression includes pass/fail analysis on the likelihood of converting a potential customer into a paying one. Logistic regression is often used in medical diagnoses—for instance, plasma glucose concentrations over a certain range are used as a strong indicator of diabetes. ...
