CODE DESIGNDo not simply start writing code!!! Attempt to write your best version first.Develop a detailed project outline.Choose the best tool for the job (SAS is great for data prep and largedatasets, while Stata works well for estimating models)Break your project into discrete steps that can be developed independently.Create input data (subset, sort, and merge input files)Transform (create new variables)Statistical estimates (develop estimators, generate models)Output and diagnostics (create tables, graphs, and verify results)Wednesday, August 21, 13
ASSUME YOUR CODE ISWRONG!Design your code and subroutines under theassumption you will make mistakesDuring development, break your program into smallpieces and debug each section of code separatelyAdd in debugging code that will be turned offduring normal execution (i.e. put statements in SAS)Develop a prior expectation of what the results willlook like at each stageWednesday, August 21, 13
