# Calculate Hosmer Lemeshow (HL) Test with Excel

Hosmer and Lemeshow Test (HL)

It measures the association between actual events and predicted probability. In other words, it is a measure of how close the predicted probabilities are to the actual rate of events.

In HL test, null hypothesis states that sample of observed events and non-events supports the claim about the predicted events and non-events. In other words, the model fits data well.

Calculation
1. Calculate estimated probability of events
2. Split data into 10 sections based on ascending order of probability
3. Calculate number of actual events and non-events in each section
4. Calculate Predicted Probability = 1 by averaging probability in each section
5. Calculate Predicted Probability = 0 by subtracting Predicted Probability=1 from 1
6. Calculate expected frequency by multiplying number of cases by Predicted Probability = 1
7. Calculate chi-square statistics taking frequency of observed (actual) and predicted events and non-events Hosmer Lemeshow Test
Rule : If p-value > .05. the model fits data well.

1. HI Deepanshu I was looking at the attached excel for HL in excel. In the column H, you do an average of all probability (irrespective of dependent variable =0 or 1) and then put that average value in Column I. I was wondering if that is the correct way or we need to filter only those probabilities where dependent variable =1 and then average those probabilities?

1. This is the correct way. Thanks!
