Global models for the orientation field of fingerprints: an approach based on quadratic differentials.

Sep 2008 Quadratic differentials naturally define analytic orientation fields on planar surfaces. We propose to model orientation fields of fingerprints by specifying quadratic differentials. Models for all fingerprint classes... Read more...

A comparison of regression approaches for analyzing clustered data.

Aug 2008 OBJECTIVES: We used 3 approaches to analyzing clustered data to assess the impact of model choice on interpretation. METHODS: Approaches 1 and 2 specified random intercept models but differed in standard versus novel... Read more...

Individually randomized group treatment trials: a critical appraisal of frequently used design and analytic approaches.

Aug 2008 OBJECTIVES: We reviewed published individually randomized group treatment (IRGT) trials to assess researchers' awareness of within-group correlation and determine whether appropriate design and analytic methods were... Read more...
