Audit ENA Normalization, Projection, and Rotation

Separate connection accumulation from normalization and dimensional reduction, then justify whether an SVD or two-group means rotation answers the research question.

ENA Academy Lesson 12

Quantify Uncertainty Around ENA Comparisons

Use the shared synthetic design-talk dataset to practise representing the sampling uncertainty around group locations, edge differences, and effect estimates instead of treating plotted means as exact, document the decision, test a defensible alternative, and keep every interpretation tied to source evidence.

ENA Academy Lesson 13

Use Means Rotation for a Prespecified Two-Group Question

Use the shared synthetic design-talk dataset to practise deciding when the first ENA axis should align with the difference between exactly two prespecified group means, document the decision, test a defensible alternative, and keep every interpretation tied to source evidence.

Interpret SVD Dimensions and Co-registration

Use the shared synthetic design-talk dataset to practise understanding what SVD axes summarize and whether network node positions are aligned well enough with projected unit coordinates for interpretation, document the decision, test a defensible alternative, and keep every interpretation tied to source evidence.

Reproduce an ENA Model Across Implementations

Use the shared synthetic design-talk dataset to practise checking whether two ENA implementations produce equivalent accumulated connections, normalized vectors, projections, and interpretations under matched settings, document the decision, test a defensible alternative, and keep every interpretation tied to source evidence.
