<div dir="ltr">I just taught a class where students do a simple MLU analysis to get used to CHILDES. As I was doing it in class I noticed that the MLUs for Adam did not look right. His MLU for the first sample was 4.176, despite having mostly single word utterances. Any thoughts?<div><br></div><div>Peter<br><div><br></div><div><pre class="gmail-progOutput" style="box-sizing:border-box;font-family:"Courier New",Courier,monospace;font-size:14px;color:rgb(0,0,0);background-color:rgb(245,245,245)">mlu +tchi childes/Eng-NA/Brown/Adam/*.cha
