Diversity Index → EBIT regression — in DAX (Power BI)

A composite-index-driver analysis. Every step below is the same analysis rendered for DAX (Power BI) — grounded in the source, honest where DAX (Power BI) can't do a step cleanly.

Same analysis, your tool

SCORE-INDEX

convert raw group counts into a single trackable diversity metric

EthnicityDiversityIndex = DIVIDE([sum_of_items], n)   -- mean of the ethnic diversity items

SCORE-INDEX · mechanical

same index treatment for gender composition

GenderDiversityIndex = DIVIDE([sum_of_items], n)   -- mean of the gender diversity items

REGRESS

estimate how each diversity index moves EBIT

DAX (Power BI) can’t do this cleanly

REGRESS has no clean dax form —

VALIDITY · mechanical

keep only a statistically reliable model

-- criterion validity = Pearson measure of [measure] vs [criterion] (see CORRELATE)

PREDICT

translate diversity indices into a bottom-line forecast

Score = [b0] + [b1]*[x1] + [b2]*[x2]   -- apply the fitted coefficients (calc column)

Honest note: DAX (Power BI) can’t do 1 of these steps cleanly — the switcher shows which tools can.
