Announcements

Description

The first half of the course will be an introduction to multivariate statistical techniques commonly used in linguistics and communications. It will be accompanied by lab sessions using the statistical package R. The rest of the course revolves around seminar presentations by participants. Presentations primarily concern statistical or methodological issues in the research of the participants. See below for some of the topics presented and discussed from 2004 through 2011.

Topics for the second half include a selection from permutation tests; bootstrapping; analysis of variance and analysis of covariance; regression including multiple regression and hierarchical (multi-level) regression; dimension reduction techniques including factor analysis, principal component analysis, multidimensional scaling and/or latent semantic analysis; analysis of nominal data including association strength, Cohen's kappa, binomial or multinomial models, Fisher's exact test, odds ratios, information-theoretic inspired measures such as pointwise mutual information, or logistic regression. Other topics have regularly been presented, mostly at the request of the participants.

Prerequisites

Participants in the course should have completed a basic course in statistics covering topics such as descriptive statistics but also basis hypothesis testing using z-tests, t-tests, and χ² Participation in the first semester Research Master course on statistics and corpus linguistics (Wander Lowie and Gertjan van Noord) is strongly recommended for anyone who's never taken statistics. It is required that you know the statistics from that course, so if you've never taken such a course, that's a good basis. The statistics course given in the European Master's in Clinical Linguistics is also good.

Requirements

All participants, including auditors not taking the course for credit, must present at least one hour-long session (30 min. presentation plus 15 min. discussion and question session) on a statistical analysis technique. In addition students taking the course for credit in the research master must turn in a 8-10 pp. (2,000-2,500 wd.) paper, which may be on the same statistical analysis technique, but which may also be on another. In the paper it is important to embed the discussion in the analysis of concrete data, to explain how the analysis works, under what conditions it may be applied, and what its shortcomings are. Graphical presentations of the data attempting to illustrate the tendency that is to be proven or disproven are definitely valuable.

It is fine with me if you turn in a paper reporting on work for another course as long as the paper turned I receive focuses on the statistical analysis. If you want turn in the same paper for two course, make sure that both instructors know this and agree to it.

Ph.D. candidates from BCN or the Graduate School in the Humanities have received credit for this course in the past if they presented one topic (45 min. -- (30 + 15)) and participated regularly. I assume that that will continue to be the case.

Books

In general, we will try to use the following:
Other references that have also been found useful are the following: Many also find the more "how-to" books useful. The following books have been found especially valuable as they provide very practical instructions for doing analysis in SPSS or R. Articles may also be used from time to time. The books are on reserve, most at the Letteren library, reserve shelf. Please note that books on reserve at the Letteren library that normally belong there are not moved to the reserve shelf. Instead, they're kept at their normal places (use the catalogue), but are on reserve and cannot be loaned out.
