Most commonly, this includes predicted values in the <code>.fitted</code> column, residuals in the <code>.resid</code> column, and standard errors for the fitted values in a <code>.se.fit</code> column. New columns always begin with a <code>.</code> prefix to avoid overwriting columns in the original dataset. </p> <p>Users may pass data to augment via either the <code>data</code> argument or the <code>newdata</code> argument. If the user passes data to the <code>data</code> argument, it <strong>must</strong> be exactly the data that was used to fit the model object. Pass datasets to <code>newdata</code> to augment data that was not used during model fitting. This still requires that all columns used to fit the model are present. </p> <p>Augment will often behave differently depending on whether <code>data</code> or <code>newdata</code> is given. This is because there is often information associated with training observations (such as influences or related) measures that is not meaningfully defined for new observations. </p> <p>For convenience, many augment methods provide default <code>data</code> arguments, so that <code>augment(fit)</code> will return the augmented training data. In these cases, augment tries to reconstruct the original data based on the model object with varying degrees of success. </p> <p>The augmented dataset is always returned as a <a href="../../tibble/html/tibble.html">tibble::tibble</a> with the <strong>same number of rows</strong> as the passed dataset. This means that the passed data must be coercible to a tibble. At this time, tibbles do not support matrix-columns. This means you should not specify a matrix of covariates in a model formula during the original model fitting process, and that <code><a href="../../splines/html/ns.html">splines::ns()</a></code>, <code><a href="../../stats/html/poly.html">stats::poly()</a></code> and <code><a href="../../survival/html/Surv.html">survival::Surv()</a></code> objects are not supported in input data. If you encounter errors, try explicitly passing a tibble, or fitting the original model on data in a tibble. </p> <p>We are in the process of defining behaviors for models fit with various <code>na.action</code> arguments, but make no guarantees about behavior when data is missing at this time. </p> <h3>Usage</h3> <pre> ## S3 method for class 'stl' augment(x, data = NULL, weights = TRUE, ...) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>x</code></td> <td> <p>An <code>stl</code> object returned from <code><a href="../../stats/html/stl.html">stats::stl()</a></code>.</p> </td></tr> <tr valign="top"><td><code>data</code></td> <td> <p>Ignored, included for consistency with the augment generic signature only.</p> </td></tr> <tr valign="top"><td><code>weights</code></td> <td> <p>Logical indicating whether or not to include the robust weights in the output.</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>Additional arguments. Not used. Needed to match generic signature only. <strong>Cautionary note:</strong> Misspelled arguments will be absorbed in <code>...</code>, where they will be ignored. If the misspelled argument has a default value, the default value will be used. For example, if you pass <code>conf.lvel = 0.9</code>, all computation will proceed using <code>conf.level = 0.95</code>. Additionally, if you pass <code>newdata = my_tibble</code> to an <code><a href="reexports.html">augment()</a></code> method that does not accept a <code>newdata</code> argument, it will use the default value for the <code>data</code> argument.</p> </td></tr> </table> <h3>Value</h3> <p>A <a href="../../tibble/html/tibble.html">tibble::tibble</a> with one row for each observation in the original times series: </p> <table summary="R valueblock"> <tr valign="top"><td><code><code>.seasonal</code></code></td> <td> <p>The seasonal component of the decomposition.</p> </td></tr> <tr valign="top"><td><code><code>.trend</code></code></td> <td> <p>The trend component of the decomposition.</p> </td></tr> <tr valign="top"><td><code><code>.remainder</code></code></td> <td> <p>The remainder, or "random" component of the decomposition.</p> </td></tr> <tr valign="top"><td><code><code>.weight</code></code></td> <td> <p>The final robust weights, if requested.</p> </td></tr> <tr valign="top"><td><code><code>.seasadj</code></code></td> <td> <p>The seasonally adjusted (or "deseasonalised") series.</p> </td></tr> </table> <h3>See Also</h3> <p><code><a href="reexports.html">augment()</a></code>, <code><a href="../../stats/html/stl.html">stats::stl()</a></code> </p> <p>Other decompose tidiers: <code><a href="augment.decomposed.ts.html">augment.decomposed.ts</a>()</code> </p> <hr /><div style="text-align: center;">[Package <em>broom</em> version 0.7.0 <a href="00Index.html">Index</a>]</div> </body></html>
