Homework 4 simulation program

hw4.do, a script for running the simulation

Homework 3 data and simulation program

hw3.do, a script for running the simulation
You need this plus a data set.

You may use gpa.dta (a smaller version of the simluation data set) or the full csdata.dta (described in the textbook). As before, multiple forms of the data sets are below. Remember to use Netscape!

gpa version
- gpa.dta
  . use gpa or
  . use d:\gpa or similar.
- gpa.dct
  . infile using gpa or
  . infile using d:\gpa or similar.
- gpa.raw
  . infile gpa using gpa
  . infile gpa using d:\gpa
Full CSDATA versions
- csdata.dta
  . use csdata
  or similar.
- csdata.dct
  . infile using csdata
  or similar.
- csdata.raw
  . infile id gpa hsm hss hse satm satv using csdata
  or similar.

Homework 2 Data:
(If the .dta version of the data set does not work, a couple of alternatives are provided below. You use a different command to load the data depending on where it is located on your computer.)

New: Versions of the data set containing only the variables needed for the assignment have been added below. They are referred to as salarysmall data sets.
You may use either version for hw 2.

salarysmall data sets.
- salarysmall.dta (for assignment 2)
  Load into Stata using one of the following or something similar:
  . use salarysmall
  . use C:\salarysmall
  . use D:\salarysmall
- salarysmall.dct (for assignment 2)
  . infile using salarysmall
  . infile using C:\salarysmall
  . infile using D:\salarysmall
- salarysmall.raw (for assignment 2)
  . infile str6 Gender Startyr Sal0 Sal91
  . infile str6 Gender Startyr Sal0 Sal91
  . infile str6 Gender Startyr Sal0 Sal91
Full salary data sets.
- salary.dta (for assignment 2)
  Load into Stata using one of the following or something similar:
  . use salary
  . use C:\salary
  . use D:\salary
- salary.dct (for assignment 2)
  . infile using salary
  . infile using C:\salary
  . infile using D:\salary
- salary.raw (for assignment 2)
  . infile ID str6 Gender Startyr Deptcode Sal0 Sal91
  . infile ID str6 Gender Startyr Deptcode Sal0 Sal91
  . infile ID str6 Gender Startyr Deptcode Sal0 Sal91

Thursday, January 4, One computer note

In USITE, when you try to download the data set, you must tell the computer to put it in a directory to which you have permission to write. If it does not happen automatically, try the D:\ directory. If it still does not work, please ask a USITE user assistant where you can write a file for temporary usage.

Homework 1 Data:

table6.dta, table 6, chapter 1, IPS.
When you click on this link, it may appear that nonsense numbers appear inside the frame on the screen. This happens because Netscape is not sure what to do with the Stata-type data set. Click on the panel that has the nonsense, then select under File the option "Save Frame As". You should be asked whether you want to save table6.dta. Do so, then in Stata, type . use table6 or . use c:\table6 to get table6 into Stata.
table6full.dta, full table corresponding to table 6, chapter 1, IPS -- see the data appendix D-3 in IPS. This is provided for your reference only.
When you click on this link, it may appear that nonsense numbers appear inside the frame on the screen. This happens because Netscape is not sure what to do with the Stata-type data set. Click on the panel that has the nonsense, then select under File the option "Save Frame As". You should be asked whether you want to save table6full.dta. Do so, then in Stata, type . use table6full or . use c:\table6full to get table6full into Stata.
(If the above does not work, here are some more versions. See Hamilton, Statistics with Stata 5, for more details on these versions.)

table6.dct table 6, Data Dictionary Format. Save to Desktop, then type in Stata
. infile using table6 or
. infile using c:\table6
table6.raw table 6, raw text format. Save to Desktop, then in Stata
. infile id gpa iq age sex sc c1 c2 c3 c4 c5 c6 using table6.raw or
. infile id gpa iq age sex sc c1 c2 c3 c4 c5 c6 using c:\table6.raw
