  of the likelihood function, allowing distributional models.
  
  Parameters
  ----------
  formula : str
      A model description written using the formula syntax from the ``formulae`` library.
  *additionals : str
      Additional formulas that describe the
code: def __init__(self, formula: str, *additionals: str):
      self.additionals_lhs = []
      self.main = formula
      self.additionals = self.check_additionals(additionals)
