the opening /* as well as the closing */, which may be some characters or this may perhaps span several strains, is actually a comment to get disregarded by Stata. This type of remark can be used anyplace, even in the midst of a line, and is typically utilized to "remark out" code.
Wbopendata attracts from the main Environment Lender collections of progression symptoms, set with each other from officially-recognized worldwide sources. It offers probably the most exact and present international advancement information available, and likes all over the entire world, regional and Intercontinental price estimates.
The tag (inside the STB the insert amount) indicates the Model on the file. Suppose st0067 gives some characteristic. st0067_1 should really supply all precisely the same attributes and become better than st0067. st0067_2 must be the identical factor but much better than the two that preceded it, etc. We are saying “commonly” only for the reason that authors and editors at times make issues.
The capabilities really figure out just what the egen command will do. There are lots of of them, all explained in help egen, and the next sectios of this action will explain using the mostly made use of features. These examples will with any luck , explain the way to use the several features and how can they help us.
Sorry, but I don’t comprehend your dilemma. The null hypothesis is what ever you desire it for being as explained around the referenced webpage.
