Where are we and what should I be doing?

December 4:

Do the following homework.
Nothing has to be handed in, this is to prepare for the final and learn.
Solutions are already included.

Do all of the Simple Linear Regression Homework.
"Homework and Solutions: Simple Linear Regression"

Do all of the Multiple Regression Homework.
"Homework and Solutions: Multiple Regression"

Do all of the Topics in Regression Homework.
"Homework and Solutions: Topics in Regression"


You can have two hand-written cheat sheets
with writing on all four sides.
You can use your cheat sheets, a pen, and a calculator.

Review the midterm and homework since the midterm.

Review the two old finals on the webpage:

07 final: Q1, Q2, Q3, Q4 (a-f), Q5, Q7 (a,b), Q8,
Q9 (not part 9, not part 17), Q10, Q11

12 final: Q1, Q3, Q4, Q5, Q6, Q7 (1 and 2), Q8, Q9,
Q10 (not part 12, not part 14), Q11, Q12

2016 Midterm: All questions.
Note that in the first question of the 2016 midterm the dependent variable we are trying to predict is 1 if an account defaults and 0 otherwise.
Each bottom node has estimates of the probability of a default and 1 minus that.
So, for example, in the node at the far right there is a .237 prob of not defaulting and a .763 prob of defaulting.

November 18:

We stopped at the "Predictive Interval" in section 3 of the Simple Linear Regression notes.

Do all the homework from the notes on Confidence intervals and hypothesis tests:
"Homework: Confidence Intervals, Hypothesis Tests, and p-values"

Do 1.1 and 3.1 (a)-(e) of the Simple Linear Regression Homework:
"Homework: Simple Linear Regression"

November 4:

We stopped at the beginning of Section 3 in the notes on ``Linear Combination, Covariance and Correlation''.

Homework is:
3.1, 3.2, and 3.3 (all the problems) from Homework: "Modelling with IID Normal Draws"
1.1, 1.2, and 2.1 from Homework: "Linear Combination, Covariance and Correlation"

October 21:

We stopped at the slide titled ``Long Run Average of IID Draws''
in the last section (number 5) of the notes Continuous Distributions.

Remember, next time we have the midterm on Friday afternoon, 2:30-4:30.
Andreas and/or I will be available to answer questions 1pm - 2:15.
The midterm will cover everthing we have done.

To prepare for the midterm do all of the homework currently on the webpage.
That is:
Homework, with Solutions: "Discrete Random Variables, Mean and Variance"
Homework, with Solutions: "Conditional Distributions and Joint Distributions"
Homework, with Solutions: "Continuous Distributions"

You do not have to hand in the homework this time.
Solutions are already included with the homework.
(Note that the solutions have the notes, the homework and the solutions, so you can
see where the problems fit in the notes.)

For the test you can have one "cheat sheet" with hand written notes (you can write on both sides).
Other than that, you just need a pen and a calculator (not a pencil).

To study for the midterm, do the homework and also have a look at:
Fall 2015, Quiz 1 (all)
Fall 2015, Quiz 2 (all)
2012 Final, Questions 1, 3, 4.1-4.8 (not 4.9), 6.1-6.4, 7.1, 9.1-9.3, 11.1-11.5.
2007 Final, Questions 1, 2, 3 (except part (i)), 4 (a-c), 10.
2016 Midterm, everything except skip Question 1.

October 7:

We stopped at slide 15 of the notes
"Discrete Random Variables, Mean and Variance".

Homework due is both questions of Homework "Looking at Data" and "Capturing Relationships with Linear Regression".

Homework is due on our next Saturday, October 21.
Contact Andreas for details on handing in the homework.

There is not a ton of homework, but I'm hoping you spend some time playing around in R and Excel.

September 19:

Nothing to be done at this time except maybe have a look at Excel and or R.
See the links on the main webpage.

It might help if you install R before the first class.

The swirl stats for learning R looks cool!!
