Principal Component Analysis

Experience a completed Principal Component Analysis exactly as it appears inside Statistico.

Adjust retention and rotation interactively; eigenvalues, scree evidence, loadings, biplots, and score plots respond together.

Designed for serious statistical analysis inside Excel.

Why analysts choose Statistico

Instead of isolated statistical outputs, Statistico keeps every stage of Principal Component Analysis connected — without leaving the analytical workflow.

From correlation structure to statistical reasoning — this is Interactive Statistical Computing, not a sequence of static outputs.

Retention

Retention guidance is part of the PCA workflow

Kaiser and scree-elbow guidance sit next to the eigenvalue table, and hovering a scree point can highlight the matching row so retention is a visible decision.

Structure

Assess loadings, rotation, and case-level maps

Loadings, biplot, contribution, and outlier views keep variable structure and case behavior connected.

Visualization

Move from components to biplots and score maps

Biplot and score views use the same retained solution, so visualization does not restart the reduction.

Interpretation

Interpretation within the analytical workflow

Statistico's AI-assisted assessment summarizes retention, loadings, and structure cues from the same PCA output already in the workspace.

AI-assisted interpretation supports, but does not replace, statistical judgment.
Why Statistico

Built for analysts who already know the method

Excel remains the working data environment.

Statistical outputs remain visible and inspectable.

Interaction supports analysis rather than hiding it.
