Differences in calculation for Naive net in WEKA
<p>I tried out Naive net in weka 3.8 using weather dataset
Weka results</p>

<h2>OUTLOOK</h2>

<p>Sunny Yes = 0.238
      No = 0.538</p>

<p>Overcast Yes = 0.429
         No = 0.077</p>

<p>Rainy Yes = 0.333
      No = 0.385</p>

<h2>TEMPERATURE</h2>

<p>Hot Yes = 0.238
      No = 0.385</p>

<p>mild Yes = 0.429
         No = 0.385</p>

<p>Cool Yes = 0.333
      No = 0.231</p>

<p>But when I workedout it manually.My results are</p>

<h2>OUTLOOK</h2>

<p>Sunny Yes (2/9)= 0.22
      No (3/5)= 0.60</p>

<p>Overcast Yes (4/9)= 0.44
         No (0/5)= 0</p>

<p>Rainy Yes (3/9)= 0.333
      No (2/5)= 0.40</p>

<h2>TEMPERATURE</h2>

<p>Hot Yes (2/9)= 0.222
      No (2/5)= 0.40</p>

<p>mild Yes (4/9)= 0.444
         No (2/5)= 0.40</p>

<p>Cool Yes (3/9)= 0.333
      No (1/5)= 0.20</p>

<p>Why is this difference?
Whether my calculation went wrong somewhere?</p>
