Diversity Index → EBIT impact — in SQL

A composite-index-regression analysis. Every step below is the same analysis rendered for SQL — grounded in the source, honest where SQL can't do a step cleanly.

Same analysis, your tool

SCORE-INDEX

convert raw headcount breakdowns into one trackable diversity metric

items / n AS EthnicityDiversityIndex

SCORE-INDEX · mechanical

same index treatment for the gender dimension

items / n AS GenderDiversityIndex

REGRESS

estimate how diversity indices move earnings before interest and taxes

SQL can’t do this cleanly

REGRESS has no clean sql form —

VALIDITY · mechanical

confirm the diversity-EBIT relationship is reliable

corr(measure, criterion)

PREDICT

quantify the business value of increasing diversity

SQL can’t do this cleanly

PREDICT has no clean sql form —

Honest note: SQL can’t do 2 of these steps cleanly — the switcher shows which tools can.
