topic sample size for the categories of a nominal variable in Statistical Procedures https://communities.sas.com/t5/Statistical-Procedures/sample-size-for-the-categories-of-a-nominal-variable/m-p/916646#M45471 <P>I have a nominal variable with 3 categories. I am running a GEE model as the response variable is repeated in 2 scenarios. Following is a table with the sample size for both scenarios. As shown in the Table, the sample size for category 3 is only 6 and 1 in scenario 1 and scenario 2, respectively.</P><P>I searched in Google to find out whether it is possible to run multinomial GEE model with this small sample size but could not find anything. That is why I am reaching out to this community to learn if there is any requirement for sample size for every category of a nominal variable. &nbsp;</P><P>&nbsp;</P><TABLE><TBODY><TR><TD>&nbsp;</TD><TD>Category 1</TD><TD>Category 2</TD><TD>Category 3</TD><TD>Total</TD></TR><TR><TD>Scenario 1</TD><TD>18</TD><TD>10</TD><TD>6</TD><TD>34</TD></TR><TR><TD>Scenario 2</TD><TD>20</TD><TD>13</TD><TD>1</TD><TD>34</TD></TR></TBODY></TABLE> Sun, 18 Feb 2024 01:56:38 GMT tan1721 2024-02-18T01:56:38Z sample size for the categories of a nominal variable https://communities.sas.com/t5/Statistical-Procedures/sample-size-for-the-categories-of-a-nominal-variable/m-p/916646#M45471 <P>I have a nominal variable with 3 categories.
