Extreme AIC in glm(), perfect separation, svm() tuning
...e. The prediction error of itself by glm() is
0! brglm() is no better than glm() in this case. Code and output of glm():
matrix2 <- read.table("http://ihome.ust.hk/~haitian/sample2.txt")
names(matrix2)<- c("g0","g28","g1334","g1871","g3639","g4295")
library(MASS)
fo2 <- as.formula(g0 ~ g28 * g1334 * g1871 * g3639 * g4295)
lr2 <- glm(fo2, family=binomial(link=logit), data=matrix2)
summary(lr2)
