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 \(x=0\).
