<h1>WEIBULL.DIST Function</h1>
|
|
<p>The <b>WEIBULL.DIST</b> function is one of the statistical functions. It is used to return the Weibull distribution. Use this distribution in reliability analysis, such as calculating a device's mean time to failure.</p>
|
|
<p>The <b>WEIBULL.DIST</b> function syntax is:</p>
|
|
<p style="text-indent: 150px;"><b><em>WEIBULL.DIST(x, alpha, beta, cumulative)</em></b></p>
|
|
<p><em>where</em></p>
|
|
<p style="text-indent: 50px;"><b><em>x</em></b> is the value between at which the function should be calculated, a numeric value greater than or equal to 0.</p>
|
|
<p style="text-indent: 50px;"><b><em>alpha</em></b> is the first parameter of the distribution, a numeric value greater than 0.</p>
|
|
<p style="text-indent: 50px;"><b><em>beta</em></b> is the second parameter of the distribution, a numeric value greater than 0.</p>
|
|
<p style="text-indent: 50px;"><b><em>cumulative</em></b> is 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.</p>
|
|
<p>The values can be entered manually or included into the cells you make reference to.</p>
|
|
<p>To apply the <b>WEIBULL.DIST</b> function,</p>
|
|
<ol>
|
|
<li>select the cell where you wish to display the result,</li>
|
|
<li>click the <b>Insert function</b> <img alt="Insert function icon" src="../images/insertfunction.png" /> icon situated at the top toolbar,

|
|
<br />or click the <img alt="Function icon" src="../images/function.png" /> icon situated at the formula bar,
|
|
</li>
|
|
<li>select the <b>Statistical</b> function group from the list,</li>
|

<li>enter the required arguments separating them by commas,</li>
|
|
<li>press the <b>Enter</b> button.</li>
|
|
</ol>
|
|
<p>The result will be displayed in the selected cell.</p>
