In Addition to my previous question, i would like to understand, what would be acceptable R-square value for ordinal regression? is it realist to expect to R-square > 0.50? Regards Mahadevan.S

i am doing ordinal logistic regression using minitab, please find the results as below. when i asked my friend to cross check the results in "R" for the same data set, i was surprised to see different results come up. what was even more peculiar is that the coef no's seem to be similar however Minitab was showing -ve values where "R" was throwing +ve values and vice versa. i am curious to know why this happens and which result should i consider?
