Scott Long is Distinguished Professor and Chancellor's Professor of Sociology and Statistics at Indiana University, Bloomington. He teaches quantitative methods both at Indiana University and at the ICSPR Summer Program. His earlier research examined gender differences in the scientific career. In recent years, he has collaborated with Eliza Pavalko, Bernice Pescsolido, John Bancroft, Julia Heiman and others in studies of health and aging, stigma and mental health, and human sexuality.

Soc 751: The workflow of data analysis (1st Summer Session 2013; May 7 orientation. May13-May 24: Lectures and labs. May 27-31: Independent work) This intensive class deals with the entire process of research: planning, documenting, and organizing your work; creating, labeling, naming, and verifying variables; performing and presenting statistical analyses; preserving your work; and, critically, producing replicable results. Most classes in statistics focus on estimating and interpreting models. In "real world" research, these activities often involve less than 10% of the total work. This workshop is about the other 90% of the work. Contact Scott Long for authorization to enroll. 25Feb2013

Workflow in Data Analysis. The Workshop in Methods is this talk by Scott Long on Friday, September 3 at 2:30 in Woodburn Library Room 200. A recent entry on a blog discussing Professor Long’s recent book, The Workflow of Data Analysis Using Stata, claimed: “The publication of [this book] may even reduce Indiana’s comparative advantage of producing hotshot quant PhDs now that grad students elsewhere can vicariously benefit from this important aspect of the training there.” 1Sep2010

Stata 11 and SPost: Due to changes in Stata 11, prchange and countfit sometimes ran incorrectly. As of 31Jul2009 these ado files have been updated to prchange (v 1.8.1) and countfit (0.8.1) to work with Stata 11. If you encounter problems, let me know.

SPost and factor variables: spost9_ado does not work with factor variables in Stata 11.

Workshop on Categorical Data Analysis for ICPSR's Summer Program in 2008. The class is was held in Ann Arbor, Michigan from June 9, 2007 to June 13, 2008. The workshop examines the most important regression models for binary, ordinal, nominal and count outcomes. A variety of practical methods for interpreting the nonlinear models are presented. Statistical testing and assessing fit is also illustrated with a series of real-world examples. For further information, check here.
