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: 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 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 کاملNeural Clustering: Concatenating Layers for Better Projections
Effective clustering can be achieved by mapping the input to an embedded space rather than clustering on the raw data itself. However, there is limited focus on unsupervised transformation methods that improve clustering and classification accuracies. In this paper, we introduce Neural Clustering1, a simple yet effective unsupervised model to project data onto an embedded space where intermedia...

My interest began in elementary school with my parents playing cassette tapes of great speakers during long road trips. Those speakers inspired me through their words and I in turn began to desire to inspire others through speech. In high school, I pursued speaking through joining the forensic...
