I'm conducting a binary logistic regresion. My independent variables are scores on the range of 0 till 100. Only full numbers are possible, no 1.5 for example. So, I think that my variables are not continuous. When I'm reading about the box Tidwell test I need to check linearity between the dependent variable and the continuous predictors, but my research doesn't have continuous predictors. Now I'm wondering if I should skip the Box Tidwell test. And is there another test for linearity that I could use?
