Web2 days ago · I have fitted a poisson and a negative binomial distribution to my count data using fitdist()in fitdistplus. I want to assess which is the better fit to my data set using the gofstat()function but I would like to check if my interpretation, that a negative binomial is a better fit, is correct. Websvm can be used as a classification machine, as a regression machine, or for novelty detection. Depending of whether y is a factor or not, the default setting for type is C-classification or eps-regression, respectively, but may be overwritten by setting an explicit value. Valid options are: C-classification. nu-classification.
