@KirtikaKataria

Hi there, I understand you need help testing hypotheses using a linear mixed model on longitudinal data, specifically to evaluate treatment effects over time. The goal is to model repeated measures correctly, account for within-subject correlations, and provide valid statistical inference for your treatment hypotheses. My approach is to set up a linear mixed model using R, Python, or SAS (based on your preference), define fixed effects for treatments and time points, and random effects for subjects or clusters as appropriate. I will perform hypothesis testing, check model assumptions, and generate interpretable outputs such as estimated treatment effects, confidence intervals, and p-values. Diagnostic plots and sensitivity checks can also be included to ensure robustness. Deliverables will include a fully coded, reproducible model with annotated scripts, a summary of hypothesis test results, visualizations of treatment effects over time, and a concise report explaining the interpretation of findings. QUESTION: Would you like me to include interaction effects between time and treatment, or focus only on main effects? If you want accurate, reproducible longitudinal analysis with clear treatment-effect insights, I am ready to start. Regards, Shehwani.
