Research interests

• Clinical collaborations
• Explained variation, reference curve estimation, zero inflation

Techniques, methods & infrastructure

Clinical collaborations: Survival analysis, mixed models, regression models

Explained variation: Schemper-Henderson measure, degrees of necessity and of sufficiency

Reference curve estimation: generalized additive models for location scale and shape (GAMLSS)

Zero inflation: one-part tests, two-part tests, left-inflated mixture model
