Data Scientist & Survey Expert.
I have completed a Ph.D. and M.Sc. in Survey and Data Science (University of Michigan, USA). I have research articles published in well-reputed impact factor journals. I can perform data analysis using statistical software like R, Stata, SAS, SPSS, Minitab, Jamovi, Jasp, Amos, Mplus, SmartPls, EQS, IRTPRO, and LatentGold.
I can analyze/collect your data using advanced statistical methods:
- regression models (linear and generalized linear models),
- multilevel models,
- longitudinal models,
- machine learning algorithms (Lasso, Random Forest, Boosting, Naive Bayes),
- latent variable models (Structural Equation Modeling, Confirmatory Factor Analysis, Exploratory Factor Analysis, and Latent Class Analysis),
- exploratory multidimensional analysis (Principal Components Analysis, Cluster Analysis, and Multiple Correspondence Analysis, Multidimensional Scaling),
- multiple imputation of missing data,
- psychometric analysis of questionnaires (Item Response Models, Rasch Models, Confirmatory Factor Analysis),
- design/analysis of complex survey sampling (stratified multistage cluster sampling),
- design online questionnaires (SurveyMonkey, Alchemer).
