| 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. |  |

Stat 503: Categorical Data Analysis is being taught Fall Semester 2011. Enrollment information is here.
SugarSync: After Microsoft updated FileSync to FileMesh I starting having serious problems in which "synced" files were corrupted. I have moved to SugarSync which has the advantage of also syncing your files to the cloud. Prices are reasonable. For smaller projects, I continue to prefer Dropbox. 22Aug2011
ICPSR Sumer Program, July 11-15, 2011 in Berkeley, CA: Models for Categorical Outcomes Using Stata: Specification, Estimation, and Interpretation. Enrollment information is here. The course web site is under construction here. E-mail jslong@indiana.edu with questions.
Applications for Soc 751 are due February 15, 2011. First come, first served! As of February 17, 2011 there are only two seats left in the class.
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. The workflow of data analysis encompasses the entire process of scientific research: Planning, documenting, and organizing your work; creating, labeling, naming, and verifying variables; performing and presenting statistical analyses; preserving your work; and (perhaps, most important) producing replicable results. Most of our work in statistics classes focuses on estimating and interpreting models. In most “real world” research projects, these activities involve less than 10% of the total work. Professor Long’s talk is about the other 90% of the work. An efficient workflow saves time, introduces greater reliability into the steps of the analysis, and generates replicable results. 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 Workflow: notes search allows you to search notes. 31Jul2009
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.

Soc S651 - Multivariate Analysis for Social Science will be taught in Spring 2009. For details, check here. As of 2008-11-24, the class is filled with a waiting list.
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.
