Ordinal Logistic<br />
– a a11, a a22, a 3 … are the “intercepts” intercepts that satisfy the property<br />
a1 < a2 < a3… interpreted as “thresholds” of the latent<br />
variable.<br />
– Interpretation of parameter estimates depends on the<br />
software used! Check the software manual.<br />
• If the RHS = a + bX, bX a positive positi e coefficient is associated<br />
more with lower order categories <strong>and</strong> a negative<br />
coefficient is associated more with higher order<br />
categories.<br />
• If the RHS = a – bX, a negative coefficient is more<br />
associated with lower ordered categories categories, <strong>and</strong> a positive<br />
coefficient is more associated with higher ordered<br />
categories.
