Test 1% Critical 5% Critical 10% Critical Hence, I use the option trend to control for a linear time trend in (4).ĭickey-Fuller test for unit root Number of obs = 149 The null hypothesis I am interested in is that yrwd2 is a random walk process with a possible drift, while the alternative hypothesis posits that yrwd2 is stationary around a linear time trend.
#USE STATA 13 SERIES#
I begin by testing for a unit root in the series yrwd2 and yt, which correspond to data from a random walk with a drift term of 1 and a linear deterministic time trend model, respectively. 17) lists the distribution of the test statistic for four possible cases. Note that (4) is in a general form and we can restrict \(\alpha\) or \(\delta\) or both to zero for regression specifications that lead to different distributions of the test statistic. You should see correct names on screen both in the data editor and in the results window (even though the string itself remained intact).\newcommandĪnd tests whether \(\beta=0\).

Here's how to do it for the Russian language, but this works with any non-Western language, assuming you know which exactly encoding should it be. txt file) into proper encoding before loading them into Stata. Then the trick is to convert the data (in a. Currently (September 2015), no official Stata command serves the same purpose.

The source files keep their names, and a suffix is added to the destination file names. Variable names, label names and contents (including labels in different languages), string variable contents, and notes are translated.

unicode2ascii translates datasets and text files with Unicode characters to ASCII encoding and saves datasets in Stata 13 or 12 format.The official unicode translate command serves the same purpose, but the output from ascii2unicode is more compact and transparent, and you have access both to Unicode and ASCII versions of datasets and text files at the same time. Destination files take the names of the source files, and a suffix is added to the source file names. ascii2unicode translates datasets and text files with extended ASCII characters to Unicode encoding.The official unicode analyze command serves the same purpose, but the output from whichencoding is more compact and transparent. This is useful to determine the need for translation when sharing Stata files between users or computers with different versions of Stata installed. whichencoding examines the occurrence of Unicode and extended ASCII characters in Stata datasets and text files like do-files, ado-files, help files and log files.It includes three programs, which are able to convert single files or groups of files in the working directory: One way to solve the problem ( requires Stata 14) is offered by Svend Juul and Morten Frydenberg, who developed - trans_unicode-, Stata module to convert files to and from Unicode. The earlier versions of Stata (<=12), however, just couldn't display non-Western characters properly.

(Actually, even Stata 13 seems to be able do that to some extent) Update: Stata 14 officially supports Unicode/UTF-8 encoding.
