Dispersion Test for Poisson Regression Models
Description
Performs a dispersion test on a Poisson regression model to check for overdispersion. The function fits a Poisson regression model to the data using the specified columns, and then performs a dispersion test using the model.
Usage
cv14_dispersion_test(data, residue_col, cleaning_event_col)
Arguments
data |
A dataframe containing the observed data. |
residue_col |
A string specifying the response column in the model. |
cleaning_event_col |
A string specifying the explanatory variable in the model. |
Value
A dataframe object with the results of the overdispersion test, including
Author(s)

Examples
cv14_dispersion_test(data = Eq_Mic, residue_col = "Mic", cleaning_event_col = "CleaningEvent")
