Error with numeric class in GLM with Poisson distribution

WebJan 8, 2024 · From what I understand, a poisson regression in general has the shape ln (counts) = exp (intercept + beta * x + log (exposure)), i.e. the exposure is added through a fixed constant of value 1. I would like to reproduce this behaviour in my glm model, i.e. I want something like ln (counts) = exp (intercept + beta * x + k * log (exposure)) where ... WebIn Poisson regression, there are two Deviances. The Null Deviance shows how well the response variable is predicted by a model that includes only the intercept (grand mean).. And the Residual Deviance is −2 times the difference between the log-likelihood evaluated at the maximum likelihood estimate (MLE) and the log-likelihood for a "saturated … cherry haven melbourne

WebWeighted GLM: Poisson response data¶ Load data¶ In this example, we’ll use the affair dataset using a handful of exogenous variables to predict the extra-marital affair rate. Weights will be generated to show that freq_weights are equivalent to repeating records of data. On the other hand, var_weights is equivalent to aggregating data. http://duoduokou.com/r/31736229719802484308.html
