Exercise

# Interpret Poisson coefficients

Using the fitted model from the previous exercise, `model`

, you will further analyze the results by interpreting coefficients and the multiplicative effect on the mean of the response.

Recall that the multiplicative effect is computed with \(exp(\beta_1)\).

## Question

Using the model fitted in the previous exercise which is the correct interpretation of the coefficient for `width`

variable?

Use `.summary()`

to print and view model results.

Model is saved as `model`

.

### Possible answers

The estimate \(\beta_1\) is positive meaning that the effect on the mean of the response will be \(exp(\beta_1)\) times larger than if \(x=0\).

The relationship can not be determined since width value can not be zero.

The estimate \(\beta_1\) is negative meaning that the effect on the mean of the response will be \(exp(\beta_1)\) times smaller than if \(x=0\).
