In statistics, simple linear regression is a linear regression model with a single explanatory variable. That is, it concerns two-dimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a non-vertical straight line

If the t ratio for the slope of a simple linear regression equation is -2.48 and the critical values of the t distribution at the 1% and 5% levels, respectively, are 3.499 and 2.365, then the slope is...

**Lecture 9. The multiple Classical Linear Regression model**

The multiple linear regression equation is just an extension of the simple linear regression equation – it has an “x” for each explanatory variable and a coefficient for each “x”. Question: Write the least-squares regression equation for this problem.... nate because the world is too complex a place for simple linear regression alone to model it. A regression with two or more predictor variables is called a multiple regression. (When we need to note the difference, a regression on a single predic- tor is called a simple regression.) We’d never try to find a regression by hand, and even calculators aren’t really up to the task. This is a

### Rather than having a simple linear model of the form Y = 0 + 1X, you could add more predictors. Perhaps a polynomial of the form Y = 0 + 1X + 2X2 would be a better t. Along similar lines, you may be able to transform one of the variables to convert the model into a linear model. Either way (adding predictors or transforming existing predictors) we have an exciting challenge in regression
