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 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 کاملGeographic Box Plots
Traditional box plots, described by Tukey in 1977, can be biased representations of geographic or spatial variables, since they do not take into account the areas associated with the elements of geographic variables. To help solve this problem, we propose and evaluate a spatially (areally) weighted box plot, a “geographic box plot,” that can be used to describe a wide variety of geographic vari...
متن کامل1 1 Box plots : use and interpretation
Abox-and-whisker plot, often referred to as a box plot, was developed by John Tukey.1 It is a convenient graphic tool in descriptive analysis to display a group or groups of numerical data through their medians, means, quartiles, and minimum and maximum observations. A box plot is useful to display the distribution of data, examine symmetry, and indicate potential outliers and can also be used ...
