Kevin K.に依頼

United States

PhD Statistical Consultant | Mixed Effects Models, Scale Development, & Experimental Design in R

プロフィール概要

I am a PhD-level researcher specializing in advanced statistical modeling, experimental design, and psychometric scale development. My expertise lies in analyzing complex behavioral and decision-making data using rigorous, publication-ready methods. I regularly work with hierarchical and longitudinal datasets and have extensive experience with mixed-effects modeling (multilevel models), logistic regression, ordinal and multinomial models, structural equation modeling (CFA/EFA), item response theory (IRT), and scale validation procedures. I am highly proficient in R and frequently develop reproducible analytic workflows for academic manuscripts, dissertations, and grant-funded research. My research background includes large-scale behavioral experiments, survey-based measurement development, and risk-related decision-making tasks. I have designed and analyzed multi-factor experimental studies, conducted cross-validation procedures for scale development, and implemented Bayesian and frequentist modeling frameworks.
