Recall: The proportion of actual positives that were identified correctly to all actual positives
Recommendation systems: Unsupervised learning techniques that use unlabeled data to offer relevant suggestions to users
Refactoring: The process of restructuring code while maintaining its original functionality Regression analysis: A group of statistical techniques that use existing data to estimate the relationships between a single dependent variable and one or more independent variables Regression coefficient: The estimated betas in a regression model Regression models: (Refer to regression analysis)
Regularization: A set of regression techniques that shrinks regression coefficient estimates towards zero, adding in bias, to reduce variance
remove(): A method that removes an element from a list
Representative sample: A sample that accurately reflects the characteristics of a population
reshape(): A NumPy method used to change the shape of an array
Residual: The difference between observed or actual values and the predicted values of the regression line
Response variable: (Refer to dependent variable)
return: A reserved keyword in Python that makes a function produce new results which are saved for later use
