<h1>BETA.DIST Function</h1>
|
|
<p>The <b>BETA.DIST</b> function is one of the <a href="../UsageInstructions/InsertFunction.htm#statistical" onclick="onhyperlinkclick(this)">statistical functions</a>. It is used to return the beta distribution.</p>
|
|
<h3>Syntax</h3>
|
|
<p><b><em>BETA.DIST(x, alpha, beta, cumulative, [A], [B])</em></b></p>
|
|
<p>The <b>BETA.DIST</b> function has the following arguments:</p>

</tr>
|
|
<tr>
|
|
<td><b><em>x</em></b></td>
|
|
<td>The value between <b><em>A</em></b> and <b><em>B</em></b> at which the function should be calculated.</td>
|
|

|
|
<tr>
|
|
<td><b><em>alpha</em></b></td>
|
|

|
|
</tr>
|
|
<tr>
|
|
<td><b><em>cumulative</em></b></td>
|
|
<td>A logical value (TRUE or FALSE) that determines the function form. If it is TRUE, the function returns the cumulative distribution function. If it is FALSE, the function returns the probability density function.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>A</em></b></td>
|
|
<td>The lower bound to the interval of <b><em>x</em></b>. It is an optional parameter. If it is omitted, the default value of 0 is used.</td>
