  1. Advanced Methods and Models in Behavioral Research • Chris Snijders • Gerrit Rooks • 3 ects • http://www.chrissnijders.com/ammbr (=studyguide) • literature: Field book+ separate course material • laptop exam (+ assignments) ToDo: Studyweb! Enroll in 0a611 Advanced Methods and Models in Behavioral Research – 2010/2011

  2. The methods package • MMBR (6 ects) • Blumberg: algemeen: vraagstelling, betrouwbaarheid, validiteit etc • Field: SPSS: factor analyse, multiple regressie, ANcOVA, sample size etc • AMMBR (3 ects) - Field (deels): logistische regressie - literatuur via website: conjoint analysis  multi-level regression Advanced Methods and Models in Behavioral Research – 2010/2011

  3. Models and methods: topics • t-test, Cronbach's alpha, etc • multiple regression, analysis of (co)variance and factor analysis • logistic regression • conjoint analysis / repeated measures • Stata naast SPSS • “Naar nieuwe vragen” • Oefenen (een beetje) met data verzameling Achterliggende gedachte: nu moet je het zelf kunnen Advanced Methods and Models in Behavioral Research – 2010/2011

  4. Methods in brief (1) • Logistic regression: target Y, predictors Xi. Y is a binary variable (0/1). - Why not just multiple regression? - Interpretation is more difficult - goodness of fit is non-standard - ... Advanced Methods and Models in Behavioral Research – 2010/2011

  5. Methods in brief (2) • Conjoint analysis Underlying assumption: for each user, the "utility" of a product can be written as U(x1,x2, ... , xn) = c0 + c1 x1 + ... + cn xn • 10 Euro p/m • 2 years fixed • free phone • ... • How attractive is this • offer to you? Advanced Methods and Models in Behavioral Research – 2010/2011

  6. Conjoint analysis as an “in between method” Between Which phone do you like and why? What would your favorite phone be? And: Let’s keep track of what people buy. Advanced Methods and Models in Behavioral Research – 2010/2011

  7. Coming up with new ideas (3) “More research is necessary” But on what? YOU: come up with sensible new ideas, given previous research Advanced Methods and Models in Behavioral Research – 2010/2011

  8. Stata next to SPSS • It’s just better (faster, better written, more possibilities, better programmable …) • Multi-level regression is much easier than in SPSS • It’s good to be exposed to more than just a single statistics package (your knowledge should not be based on “where to click” arguments) • More stable (I think) • Supports OSX as well… (anybody?) Advanced Methods and Models in Behavioral Research – 2010/2011

  9. But … • Output less “polished” • It takes some extra work to get you started • The Logistic Regression chapter in the Field book uses SPSS (but still readable for the larger part) • (and it’s not campus software, but subfaculty software) • Installation … Advanced Methods and Models in Behavioral Research – 2010/2011

  10. Advanced Methods and Models in Behavioral Research • To Do • enroll in studyweb (0a611) • Read the Field chapter on logistic regression Advanced Methods and Models in Behavioral Research – 2008/2009 10 Advanced Methods and Models in Behavioral Research – 2010/2011
