Do you know how HR uses Logistic Regression to flag employees at risk of leaving?
It's time to unlock the power of predictive analytics to proactively manage attrition, improve retention, and keep your top talent engaged.
The High Cost of Unforeseen Attrition
Reactive retention strategies are expensive. Losing an employee costs far more than just their salary when you factor in the cascading effects on the business.
💰
Recruitment CostsAgency fees, advertising, and the dozens of hours spent on interviewing.
🎓
Training InvestmentThe time and resources poured into onboarding, development, and the ramp-up period.
📉
Lost ProductivityThe gap left during the vacancy period and the new hire's learning curve.
But what if you could anticipate who is at risk, long before they even start looking for a new job?
The Solution: Meet Logistic Regression
It's a powerful statistical method that predicts a binary outcome: an event either happens (we'll call that '1') or it doesn't ('0'). For HR, this is the perfect tool for attrition.
Instead of giving a simple 'yes' or 'no', logistic regression calculates the probability (from 0% to 100%) of an employee leaving, based on their unique data profile. This allows for a much more nuanced and targeted approach to retention.
Step 1: Gathering the Clues
A predictive model is only as good as the data it learns from. The more relevant the clues you provide, the more accurate the prediction will be. Fortunately, most of this data already exists within your HR systems.
Key data points to feed the model often include:
😊
Satisfaction Scores⭐
Performance Ratings📊
Compa-Ratio💼
Tenure / Time in Role🗓️
Time Since Promotion👥
Team Size / ManagerStep 2: Weighing the Evidence
Crucially, not all clues are created equal. The logistic regression model analyzes your historical data to learn which factors are the most powerful predictors of attrition, assigning a "weight" to each one.
High Impact Factors
- Low Satisfaction
- Low Compa-Ratio
⚖️
Lower Impact Factors
- Commute Distance
- Team Size
For example, the model might learn that a low satisfaction score is a much stronger predictor (a heavier weight) of an employee leaving than their commute distance.
Step 3: Calculating the Attrition Score
The model combines all the weighted clues for an employee into a single score. This score is then passed through a Sigmoid function, which neatly transforms it into an intuitive probability.
Probability of Leaving vs. Evidence Score
100%50%0%
Low RiskHigh Risk
Probability(Leave) = 11 + e-score
This "S-curve" is the magic that ensures the final output is always a clear probability between 0% and 100%.
Step 4: Setting the Action Threshold
A probability score is insightful, but to make it actionable, you need to define thresholds that trigger specific responses from your HR and management teams.
> 75% Risk: Immediate, high-priority intervention.
50-75% Risk: Proactive manager check-in and monitoring.
< 50% Risk: Standard engagement and development.
This simple framework turns a list of numbers into a clear, prioritized action plan.
Step 5: From Insight to Intervention
With the model running and thresholds set, your team can now move from reactive problem-solving to proactive talent management.
| Employee | Compa-Ratio | Risk Score | Action Item |
|---|---|---|---|
| Alex | 105% | 15% | Nurture & Develop |
| Ben | 85% | 78% | Conduct Salary & Role Review |
| Carla | 98% | 65% | Check in on Career Path |
Here, Ben's high risk score and low compa-ratio make him an immediate priority. Carla's medium risk also warrants a proactive conversation before it escalates.
