22 arch — Autoregressive conditional heteroskedasticity (ARCH) family of estimators arch0(xb), the default, specifies that the priming values are the expected unconditional variance of the model, which is T 1 2 t /T , where t is computed from the mean equation and any ARMA terms. arch0(...
Rather ln and atanh are directly estimated, where ln The standard error of is approximated through the delta method, which is given by ln where is the Jacobian of with respect to atanh and ln . With um likelihood estimation, this command supports the Huber/White/sandwich estimator of the ...
where the X's are held fixed and the response y is sampled at those fixed values.) Implementing this test is a matter of a few preliminaries and then, repeatedly: a call to resample and one to the stepwise regression command, followed by saving the value of T ; loop manages the details...

cmd may be any Stata command, program, or ado-file—including user-written programs or ado-files—that calculates and saves a statistic of interest. Although bs is limited to evaluating single statistics, it is not necessary that cmd calculate only one statistic. bs allows any statistic ...
Finally, consider the names of the characteristics used to store definitions of variables, a matter where there may be different preferences. By default, defv uses the same naming system as Stata's note command, so that the definitions it stores appear to have been created with note. (see ...
18.8 Accessing results calculated by other programs Stata commands that report results also store the results where they can be subsequently used by other commands or programs. This is documented in the Stored results section of the particular command in the reference manuals. Commands store results ...
Remember that Stata commands do either exactly what you say or nothing at all. We might think that our command would be guaranteed to eliminate , , and from the data if they exist. It is not. Imagine that did not exist in the data. would then do nothing. It would not drop and . ...
Panel datasets have the form , where is a vector of observations for unit and time . The particular commands (such as , , and ) are documented in alphabetical order in the entries that follow this entry. If you do not know the name of the command you need, try browsing the second ...
