MLM reading group @ Penn

UPDATE: The MLM reading group met weekly during Fall '08 at IRCS. What remains are some resources...

Short paper

Hierarchical regression for language research [IRCS Technical Report 09-02]: focuses on two studies included in the longer version, but with no attention given to implementation.

Data and code:

• Simpson's paradox simulation: [R] [csv]
• Negative concord in Philadelphia [name replaced w/ number]: [R] [csv]
• Quam and Swingley (submitted) [subject number has been scrambled]: [R] [csv]

Longer paper

Hierarchical regression modeling for language research [long version; forthcoming IRCS tech report]: similar, but includes more studies and lots of R code.

A paper given at NWAV 38

Random-effect modeling of sociolinguistic stratification: this draws on some of the material in the above papers.
