topic LCA appears to treat ordinal variables as nominal in Discussions https://community.jmp.com/t5/Discussions/LCA-appears-to-treat-ordinal-variables-as-nominal/m-p/738844#M92020 <P>When I run cluster analysis --&gt; LCA with ordinal variables (numeric, ordinal), the probability formula appears to be treating the variables as nominal, rather than ordinal. For each variable, there are 5 levels (i.e., 1-5). If being treated as ordinal, wouldn't the probability formulas reflect an order for each level where 1 may have the smallest probability and 5 the largest? As you can see below and attached, this doesn't seem to be the case. Is there a setting or function I need to change to correct for this?</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="AutoMethodsBee1_0-1711395420876.png" style="width: 400px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/62620iAB9DA89BAF968F2C/image-size/medium?v=v2&amp;px=400" role="button" title="AutoMethodsBee1_0-1711395420876.png" alt="AutoMethodsBee1_0-1711395420876.png" /></span></P><P>&nbsp;</P> Mon, 25 Mar 2024 19:41:17 GMT AutoMethodsBee1 2024-03-25T19:41:17Z LCA appears to treat ordinal variables as nominal https://community.jmp.com/t5/Discussions/LCA-appears-to-treat-ordinal-variables-as-nominal/m-p/738844#M92020 <P>When I run cluster analysis --&gt; LCA with ordinal variables (numeric, ordinal), the probability formula appears to be treating the variables as nominal, rather than ordinal.
