What it’s about

Written by a mathematician-turned-practitioner, this open-source handbook fills a critical gap for people analytics professionals who need to move beyond gut instinct and borrowed best practices toward evidence-based decisions. It treats regression as the indispensable 'Swiss army knife' of people analytics, walking the reader from statistical foundations through linear, binomial, multinomial, ordinal, mixed, structural equation, and survival models. Each method is grounded in a relatable problem, demystified with just enough mathematics to interpret outputs credibly, and demonstrated with reproducible code on realistic data sets. The book emphasizes inference (understanding why something happens) over pure prediction, reflecting the reality of small, consequential people data sets, and equips analysts to defend, critique, and communicate their models to non-statistical stakeholders.

The through-line

Who it’s for
A people analytics practitioner or analytics student who wants to deliver more targeted, credible, evidence-based insights to their organization.
The problem
They face messy, often small people data sets and need to explain what drives outcomes like promotion, attrition, performance, or satisfaction. They feel under-equipped and lack confidence to run, interpret, and defend multivariate models, fearing they cannot respond to critique.
The plan
  1. Learn the statistical and programming foundations needed to model.
  2. Match the regression method to the type of outcome you are explaining.
  3. Run the model and interpret its coefficients and fit.
  4. Check the model's underlying assumptions and pursue parsimony.
  5. Communicate the inferences clearly to non-statistical stakeholders.
The payoff
Confidently selecting and applying the right regression technique to varied people analytics problems. · Producing clear, defensible, evidence-based inferences that influence organizational decisions. · Communicating model results effectively to non-statistical audiences.
