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.
A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0). The most common method for fitting a regression line is the method of least-squares.
