why are factor levels binned? r glm why is the factor level of a variable binned to binary what is the correct r model for binned factor level why use binary variable r why do r models include insignificant variables on each factor level if one variable in r is a binary variable does it have a positive bias? why are r factors binary why are factor levels in r binary which variable is binary if only the first two are significant what variables can be converted into binary why is r converting variables into binary does r model binary factors why is each variable binned to a binary variable in r why are factor units in r binary what type of model do you run on binary r if factor level is binary what is the correct glm what is the correct model conversion for binary variable why is factor binned in r regression when is factor binary in r what type of variable does r run as a binary variable
