Dataset and scripts associated with the manuscript “A Comparative Evaluation of Classical and Gaussian AHP in Flood Fragility Environmental Analysis”. The repository contains the complete Python workflow used to calculate and compare the Classical Analytic Hierarchy Process (AHP) and Gaussian Analytic Hierarchy Process (AHP-G) models for flood-fragility assessment in the coastal municipality of Praia Grande, São Paulo, Brazil. The files include geoenvironmental flood-fragility scores adapted from Crepani (2001), pairwise comparison matrices, Gaussian weighting procedures, inferential statistical analyses (Shapiro–Wilk, Pearson, Spearman, Kendall Tau, paired t-test, Wilcoxon, ANOVA, and Kruskal–Wallis), sensitivity metrics (RMSE, MAE, variance, and standard deviation), and comparative ranking analyses. The Excel spreadsheet contains all intermediate and final outputs generated by the scripts, including normalized matrices, multicriteria weights, ranking structures, ecological-function groups, and statistical results. These materials support reproducibility, transparency, and methodological validation of multicriteria environmental modeling for coastal flood-fragility assessment and spatial decision support.
