    <div>Thank you for your email, Tim.<br>
      <br>
      Yes, your interpretation looks good to me.<br>
      <br>
      Yes, &quot;Dimension&quot; or &quot;Strand&quot; is usually used of items.<br>
      <br>
      For persons, &quot;Style&quot; or &quot;Attribute&quot; - also please Google - synonym
      trait - for some other suggestions.<br>
      <br>
      In previous times, guessers vs. not-guessers was analyzed using
      Rasch outfit statistics. Please try plotting log(outfit
      mean-square) against loading. Is that an informative plot?<br>
      <br>
      Cordially,<br>
