Ancillary parameters are constrained to the value of 1 when part of either the variance and link functions, or when they are assigned a value by the user. A prime example ... Ancillary parameters are constrained to the value of 1 when part of either the variance and link functions, or they may be assigned a value by the user. However, in the latter case the model is no longer a straightforward GLM, but rather a quasi-likelihood model. A prime example ...
