Statistical Analysis and Inference

AI assistant for ANOVA, factorial designs, and experimental analysis. Compare multiple groups, detect interaction effects, and validate experimental results.

AI assistant specialized in Bayesian statistics: priors, posteriors, credible intervals, and Bayesian updating. Turn uncertainty into clear, probability-based conclusions.

AI assistant for causal inference from observational data: propensity scores, instrumental variables, and confounder control. Move beyond correlation to causation.

AI assistant for point estimation and confidence interval construction. Get precise, correctly interpreted intervals for means, proportions, and differences.

Expert AI assistant for designing and interpreting hypothesis tests (t-tests, chi-square, ANOVA). Get accurate p-values, statistical significance, and clear conclusions.

AI assistant for multivariate statistics: MANOVA, factor analysis, PCA, and discriminant analysis. Analyze complex datasets with multiple interrelated variables.

AI assistant for nonparametric tests (Mann-Whitney, Wilcoxon, Kruskal-Wallis) when data violates normality. Reliable inference for skewed or ordinal data.

AI assistant for designing sound sampling strategies: random, stratified, cluster, and systematic sampling. Ensure representative, bias-free data collection.

AI assistant for power analysis and sample size calculations. Determine the right sample size to reliably detect real effects before you collect data.
