Logistic regression and other generalised linear models
for full screen
Description
It wasn’t until the last quarter of the 20th century that a unified vision of statistical modelling emerged, allowing practitioners to see how the general linear model we have explored so far is only a specific case of a more general class of models. We could have had a fancy, memorable name for this class of models - as John Nelder, one of its inventors, acknowledged later in life (Senn 2003:127) - but back then academics were not required to undertake marketing training on the tweetabilty-factor of the chosen names for their theories; so we ended up with generalised linear models
. These models can be applied to explananda (explained
, response
, outcome
, dependent
etc. variables, our ys) whose possible values have certain constraints (such as being limited by a lower bound or constrained to discreet choices) that makes the parameters of the Gaussian (normal
) distribution inefficient in describing them. Instead, they follow some of the other exponential distributions
(and not only the exponential: cf. Gelman, Hill, and Vehtari (2020:264)), of which the Poisson, gamma, beta, binomial and multinomial are probably the most common in human and social sciences research. Their generalised linear modelling
involves mapping them unto a linear model using a so-called link function
. We will explore what all of this means in practice and how it can be applied to data that we are interested in most in our respective fields of study.
