ECON30025 - Assignment Tips/FAQs
================================

# Assignment B

> Please read the general feedback from Assignment A as well

## Tips & Clarifications
* **PART 1.4**: Please modify the ORIGINAL model, not the model in 1.3
* **PART 3**: Use input minimisation

# Assignment A

## Working with DATASETS in SAS
* Move datasets to remote server (use explorer to click & drag or copy & paste)
* Avoid the need to click-through to set current folder every session by using:
* [Using SAS Statements to Change the Current Folder](http://support.sas.com/documentation/cdl/en/hostwin/63047/HTML/default/viewer.htm#p09f1z387baplan1r0744dqujdln.htm)
`x cd "C:\Users\huangc1\Desktop\AssignmentA"`;

## Maximising Assignment readability and marks
* READ THE QUESTION
* Use the tool specified in the questions (e.g. PROC SQL not DATA; PROC IML not PROC REG)
* Make sure you're creating the exact dataset/diagram asked for in the question.
* COMMENT YOUR CODE
* I can't provide feedback on whether your code is answering the question/doing what you want if you don't comment what the code is supposed to do.
* SHOW YOUR WORKING
* Remember this subject is not purely an "Intro to SAS" course. You need to include economic intuition/interpretation, as well as details of the Linear Algebra problem you are using SAS to solve.
* In particular, you should always include a few lines of matrix algebra to show what operations you are using your PROC IML code to complete.
* USE MEANINGFUL NAMES
* Try to use meaningful names for you variables, axes, titles etc. This is help keep the code connected to the particular context of the question, and inform your analysis and explanations
* In particular, interpreting the 3x3 matrix scatterplot becomes much more intuitive if you use product names rather than UPC numbers as labels.
