%description
Provides a set of exploratory data analysis (EDA) tools for visualizing
trends, diagnosing data types for beginner-friendly workflows, and
automatically routing to suitable statistical tests or trend exploration
models. Includes unified plotting functions for trend lines, grouped
boxplots, and comparative scatterplots; automated statistical testing
(e.g., t-test, Wilcoxon, ANOVA, Kruskal-Wallis, Tukey, Dunn) with optional
effect size calculation; and model-based trend analysis using generalized
additive models (GAM) for count data, generalized linear models (GLM) for
continuous data, and zero-inflated models (ZIP/ZINB) for count data with
potential zero-inflation. Also supports time-window continuity checks,
cross-year handling in compare_monthly_cases(), and ARIMA-ready
preparation with stationarity diagnostics, ensuring consistent parameter
styles for reproducible research and user-friendly workflows.Methods are
