<h1>TREND Function</h1>
|
||
<p>The <b>TREND</b> function is one of the statistical functions. It is used to calculate a linear trend line and returns values along it using the method of least squares.</p>
|
||
<p>The <b>TREND</b> function syntax is:</p>
|
||
<p style="text-indent: 150px;"><b><em>TREND(known_y’s, [known_x’s], [new_x’s], [const])</em></b></p>
|
||
<p>where</p>
|
||
<p><b><em>known_y’s</em></b> is the set of y-values you already know in the <em>y = mx + b</em> equation.</p>
|
||
<p><b><em>known_x’s</em></b> is the optional set of x-values you might know in the <em>y = mx + b</em> equation.</p>
|
||
<p><b><em>new_x’s</em></b> is the optional set of x-values you want y-values to be returned to.</p>
|
||
<p><b><em>const</em></b> is an optional argument. It is a TRUE or FALSE value where TRUE or lack of the argument forces <em>b</em> to be calculated normally and FALSE sets <em>b</em> to 0 in the <em>y = mx + b</em> equation and m-values correspond with the <em>y = mx</em> equation.
|
||
