Cumulative logistic regression model
WebIts cumulative distribution function is the logistic function, which appears in logistic regression and feedforward neural networks. It resembles the normal distribution in shape but has heavier tails (higher kurtosis ). The logistic distribution is a special case of the Tukey lambda distribution . Specification [ edit] WebThe estimated model can be written as: l o g i t ( P ^ ( Y ≤ 1)) = 2.20 – 1.05 ∗ P A R E D – ( − 0.06) ∗ P U B L I C – 0.616 ∗ G P A l o g i t ( P ^ ( Y ≤ 2)) = 4.30 – 1.05 ∗ P A R E D – ( − 0.06) ∗ P U B L I C – 0.616 ∗ G P A In the output above, we see Call, this is R reminding us what type of model we ran, what options we specified, etc.
