Hi R-users, I would like to find the goodness of fit using Chi-suare test for my data below: xobs=observed data, xtwe=predicted data using tweedie, xgam=predicted data using gamma> xobs <- c(223,46,12,5,7,17) > xtwe <- c(217.33,39,14,18.33,6.67,14.67) > xgam <- c(224.67,37.33,12.33,15.33,5.33,15)> chisq.test(xobs, xtwe = xtwe, rescale.p = TRUE)Error in chisq.test(xobs, xtwe = xtwe, rescale.p = TRUE) : ? unused argument(s) (xtwe = c(217.33, 39, 14, 18.33, 6.67, 14.67)) chisq.test(x, p = p, rescale.p = TRUE) I'm not sure what's wrong with it.? Thank you so much for your help. ____________________________________________________________________________________ You rock.
