fit_core: Fit Core Model

In wjunger/ares: Environmental air pollution epidemiology: a library for time series analysis

Description

Fit the core model

Usage

fit_core(formula, class = "gam", ...)

Arguments

formula	the formula for the model. See formula
class	a class for the model to be used in the fitting process. Default is gam. See Details
...	further arguments for the model fitting function

Details

This function is primarily a wrapper for the real fitting function. For now, gam and glm are the allowed classes. However, other fitting methods can be added in the future. Some information is added to the resulting object and therefore the class ares is added to its inheritance. For details on GAM options and output see gam for GLM options and output see glm.

Value

An object of the same class as the one specified by class. See each class help for a list of objects returned.
