So, cumulative logit model fits well when regression model holds for underlying logistic response. Note: Model often expressed as logit[P(y j)] = j 0x. Then, j > 0has usual interpretation of ‘positive’ effect (Software may use either. Same fit, estimates except for sign)
WebFeb 21, 2024 · The most frequently used ordinal regression, ordered logistic (or more accurately ordered logit) regression is an extension of logistic/logit regression: where in logistic regression you model one coefficient that captures the relative likelihood (in log-odds) of one outcome occurring over another (i.e. 2 outcomes captured by 1 coefficient), …
