Speaking Stata: Graphing distributions
Graphing univariate distributions is central to both statistical graphics, in general, and Stata’s graphics, in particular. Now that Stata 8 is out, a review of official and user-written commands is timely. The emphasis here is on going beyond what is obviously and readily available, with pointers to minor and major trickery and various user-written commands. For plotting histogram-like display...
متن کاملSpeaking Stata: Graphing categorical and compositional data
Abstract. A variety of graphs have been devised for categorical and compositional data, ranging from widely familiar to more unusual displays. Both official Stata commands and user-written programs are available. After a stacking trick for binary responses is explained, bar charts and related displays for cross-tabulations are discussed in detail. Tips and tricks are introduced for plotting cum...
متن کاملGraphing confidence ellipses : An update of ellip for Stata 8
This paper describes an update of the ellip command for graphing confidence ellipses in Stata 8. Two of the most notable new features are the option to graph confidence ellipses around variable means and the ability to add inscribed lines. These features allow a geometric characterization of linear regression with unequal error variances, as in McCartin (2003).
متن کاملSpeaking Stata: Problems with tables, Part I
Tables in some form or another are part and parcel of data management and analysis. The main general-purpose tabulation commands, tabulate, table, and tabstat, are reviewed and compared. When these do not provide a tabulation solution, one key strategy is to prepare the material for tabulation as a set of variables, after which the table itself can be presented with tabdisp or list. This is the...
متن کاملGraphing Kendall's tau
Correlation is an important and widely used concept, and it is usually taught through word explanation or graphic description accompaniedwith a numericmeasure if such ameasure exists. In this note, we explore graphing one of the commonly used correlation measures, Kendall’s , in such a way that we display how Kendall’s is calculated and see how Kendall’s is influenced by data features. © 2006 E...
