Assignment

The tasks based on exercises from Reka:

1. Create a workflowr project

2. Create a Markdown file in the analyis folder and solve the statistics exercises.

3. Add the following code to the end of the Rmd file and set eval=TRUE (see the code in the assignment.Rmd file):

4. Build your webpage with links on the index.html

5. As the result of the assignment, send me a zip folder

Statistics exercises:

7. Use the hfi dataset from the openintro package

8. Fit a model that uses pf_expression_control to predict hf_score, or the total human freedom score.

9. Again add region to the model. Compare the slope and \(R^2\) with the model from Q8.

10. Finally fit a model with ef_money and pf_expression_control as exposures and hf_score as outcome.

11. Use a linear regression model (and scatter plot) with ef_money as exposure and pf_expression_control as outcome, to study whether ef_money has an association with pf_expression_control as well. This might validate our finding that ef_money is a confounder between pf_expression_control as exposure and hf_score as outcome from Q10.
