I am trying to perform a Pearson's chi-square goodness of fit test on my Generalized Linear Model to measure how well the model fits my data. Below is my code: ...
On this page, I am interested in the section “goodness of fit”, which is near the bottom of the page and contains the table of deviance functions. The author states that the scaled deviance, i.e. ...
I am using glm to find a model using training data and then use test data to see how well the model is behaving. My response variable is ...
I was wondering about this, especially because I was checking this thing called "clarify" which apparently does some montecarlo simulations, but I don't understand very well if it serves my purpose ...
How can I compute Pearson's $\chi^2$ test statistic for lack of fit on a logistic regression model in R?
The likelihood ratio (a.k.a. deviance) $G^2$ statistic and lack-of-fit (or goodness-of-fit) test is fairly straightforward to obtain for a logistic regression model (fit using the ...
I am searching for a good criterion to measure the "goodness of fit" in generalized linear models. To make clear: I am not searching for a criterion which gives me an answer to the question "does ...
