what is the proportion of x=1 in r what is the proportion of x for each response category? what is the relationship between polr and x? how can I account for the nonlinear behaviour of a binary predictor? determining what is the nonlinearity of a response variable how to account for the nonlinear behavior of the variable y which variable is more predictive of a medium response or high response? what is the proportion of a binomial variable what is the proportion of x in linear regression which variable is more predictive of a very high response? what predicts very high vs lowest how to account for nonlinear behaviour what is the proportion of x=1 in r how to account for a binary predictor what is the proportion for a variable x in r models what is the proportion of x = 1 for each response category? how to account for binary predictors how is a binary predictor calculated r calculates the proportion of the variable $x=1 for each response category, based on a standard polr function why is x=1 more predictive than medium
