STATA
Getting Started:
1. Go to Stata prompt and click on “Intercooled Stata”
2. In the command line type: set mem 5000k (then press “enter”)
Note: for very large files: set mem 500000k (press “enter”)
then type: set matsize 150 (press “enter” – allows 150 variables)
3. Click on “file” (upper left corner)
4. Click on “open”
5. Click on “down arrow” to use either the “c” or “a” drives
6. Click so that the desired drive reveals its files
7. Click on the file you want to load
8. To execute an operation (e.g., ordered probit) type the following in the
command line: regress (now click on the variable names as listed
on the left side of page beginning with the dependent variable –
note that using that replacing regress with “fit” will deliver many
useful diagnostics - in regression and dichotomous logit/probit a
constant is automatically included). Then press “enter.” Other
estimators: logit (for the odds ratio – instead of the log of the odds
ratio that logit yields - replace logit with logistic), probit (for marginal
effects replace probit with dprobit), oprobit, ologit (ordered
probit/logit), mlogit (multinomial logit), nlogit (nested logit) and tobit.
If using tobit, after the last independent variable type a comma and
the letters ll and ul (e.g., tobit ratio ada pover, ll ul). This censors
the model at the lower limit and upper limit (i.e., uses the lowest
and highest values as the censoring points). You can select a
censoring point [i.e., ll (17)]. If censoring is only one side, you may
use just one censor point (e.g., tobit ratio ada pover, ll) After
running a tobit model, type quadchk (if these results differ greatly
from the tobit results it means that you probably shouldn’t use the
tobit results). After probit or logit commands you can eliminate all
the convergence output by placing “nolog” at the end of the
command line: probit vote ada99, bush00, nolog
Long Command Lines: If the command you are entering is so long that it will
not fit on one line then type /// at the endpoint of the first line and continue
the command on a second line (i.e., the line below).
Reconfigure Screen: (1) click on “Prefs”; (2) click on “Manage Preferences”; (3)
click on “Load Preferences”; (4) click on “Factory Settings.” If the
something doesn’t appear as you expect, just run several equations, it will
clear up. You may need to exit and then go back into Stata.
Place STATA Results in a Word File: Using the mouse, highlight the Stata
results you want to transfer into Word. Then use “ctrl c” (control c) to
copy the Stata results. Go into Word. Use “ctrl v” (control v) to bring the
Stata results into Word. You can “lineup” the Stata results by making sure
the font is “currier new” 9 (i.e., font size or number 9). To change the font,
highlight the Stata results you have placed in Word. With the highlight on,
