How to deal with glm fit error � NA NaN Inf� for logistic regression model in R - When we create a general linear model for logistic regression model, we need to specify the distribution family as binomial. The error “NA/NaN/Inf” occurs when we d
How to find the degrees of freedom of residual from a regression model in R - To find the degrees of freedom of residual from a regression model, we can use the function df.residual along with the model object.For example, if we have a regression model s
method : smoothing method to be used. Possible values are lm, glm, gam, loess, rlm. method = “loess”: This is the default value for small number of observations. It computes a smooth local regression. You can read more about loess using the R code ?loess. method =“lm”: It fit...
