Recap

In this session we have covered a number of concepts:

• What is regression

• What the intercept is

We have cover a number of different types of regression analysis:

• Simple Linear Regression

• Muliple Linear Regression

• Logistic Regression

We have looked at what hypothesis or significance testing means for a regression model to test

• individual regression coefficients on an outcome

• the joint effect of multiple predictor variables on an outcome

As a consequence we have drawn out the link between regression and

• a t-test

• ANOVA

In summary regression is a modulular framework that can be used to test a endless range of analytical questions.
