Learning Outcomes
After studying this chapter, the reader will be able to
- Fit a simple linear regression model to a given set of data and perform a residual analysis to check the validity of the model under consideration.
- Estimate the regression coefficients using the method of least squares and carry out hypothesis testing to test whether the first‐order regression model is an appropriate fit to the given data.
- Estimate the expected response, predict future observation values, and find their confidence intervals using the given ...
