âAt the very least, helicopter parents want to know what the university is doing to help their children thrive.â âShe talks about helicopter parents, only a call away, and to the practice of turning to parents and others by phone for support with assignments.â âWorking fairly closely with UVA's professional school population over the last 5 years, I have seen countless helicopter parents.â
Linear regression. In statistics, linear regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables (or independent variables) denoted X. The case of one explanatory variable is called simple linear regression.
In Lessons 4 and 7, we learned tools for detecting problems with a linear regression model. If important predictor variables are omitted, see whether adding the omitted predictors improves the model. If the mean of the response is not a linear function of the predictors, try a different function. For example, polynomial regression involves transforming one or more predictor variables while remaining within the multiple linear regression framework.
