Pillar II · Statistical Data Analysis

From dataset to defensible answer.

Aixys runs the workhorses of applied research — ANOVA, regression, correlation, hypothesis tests, contingency analysis — on tabular data and structured study records. Every result is paired with assumptions checked, residual diagnostics, and a short narrative explaining what the statistic means in the context of the study. Workflows feel like SAS or R for analysts who do not write code daily.

01.5 · diagnostics

Assumptions checked, post-hoc shown

Every test ships with the diagnostics that determine whether the test was the right one — residual normality, variance homogeneity, outlier flags — and the post-hoc grouping that follows.

Reading: means sharing a letter (a, b, c…) are not significantly different at α = 0.05. Cultivar C2 at N3 leads the trial; C2-N2 is statistically equivalent to it, suggesting a plateau.

Reading: residuals are approximately normal and variance is homogeneous — ANOVA assumptions hold. Two values flag as outliers (|z| > 2.5). Retained per the pre-analysis plan; sensitivity check available with one click.
