Creates a new instance of the `results` R6 class. This class is designed to store various outputs from `iglm` model estimation and simulation. Users typically do not need to call this constructor directly; it is used internally by the `iglm_object`.
results(size_coef, size_coef_popularity, file = NULL)An object of class `results` (and `R6`), initialized with empty or NA structures appropriately sized based on the input dimensions.
(integer) The number of non-popularity coefficients the object should be initialized to accommodate.
(integer) The number of popularity coefficients the object should be initialized to accommodate.
(character or NULL) Optional file path to load a previously saved `results` object. If provided, the object will be initialized by loading from this file.
