Tīmeklis2024. gada 15. nov. · For example, in our regression model we can observe the following values in the output for the null and residual deviance: Null deviance: 43.23 with df = 31. Residual deviance: 16.713 with df = 29. We can use these values to calculate the X2 statistic of the model: X2 = Null deviance – Residual deviance. X2 = … Tīmeklis2016. gada 2. jūn. · 11. I am trying to model my data in which the response variable is between 0 and 1, so I have decided to use fractional response model in R.
