needs to be done on groups of observations (which are not very easily addressed in Stata), you would need to look for an appropriate egen function. – StasK Oct 21 '12 at 0:38 Fortunately in Stata it is not a difficult process to use the same sample for all four models shown above. Some background info: As I have mentioned previously, Stata stores results in temp files. You don’t have to do anything to cause Stata to store these results, but if … 2016-07-13 2019-02-11 2015-02-13 Discover how to tabulate data by one or two variables, how to create multiple oneway tables from a list of variables, and how to create all possible twoway t Stata also has a function to generate random numbers (useful in simulation), namely uniform(). It also has an extensive set of functions to compute probability distributions (needed for p-values) and their inverses (needed for critical values), including normal() for the normal cdf and invnormal() for its inverse, see help density functions for Stata has a wide array of tools to work with dates. You can have dates in years, months, or even milliseconds. In this post, I will provide a brief tour of working with dates that will help you get started using all of Stata’s tools.

ewcommand{\Phat}{\hat{{\bf P}}}\)Vector autoregression (VAR) is a useful tool for analyzing the dynamics of multiple time series. VAR expresses a vector of observed variables as a function of its own lags. Simulation. Let’s begin by simulating a bivariate VAR(2) process using the following specification, \[\begin{bmatrix} y_{1,t}\\ y_{2,t} Stata is available for Windows, Unix, and Mac computers.

If you are new to Stata we strongly recommend reading all the articles in the Stata Basics section. Descriptive statistics give you a basic understanding one or more variables and how they relate to each other.

Stata functions, like functions in any similar language, fall on a continuum, from those you know you want to those you do not know you need. If you want a logarithm, a square root, or some probability function, the only small diﬃculty is likely to be

It prints variable and value labels with labels option.

a list or range, by simply negating the function. Thus !inlist() and !inrange() can be read as “not in list” and “not in range”. These functions can reduce your typing, reduce the risk of small errors, and make your Stata code easier to read and maintain. Thus with the auto data in memory,

If we want to plot the density of a normal distribution across a range of x values, we type y=normalden(x) .
