**Further Output**then click**Residual Plots**.

## Available data

This lists variates that can be used for the added variable or coordinates for locations. Double-click a variate name to copy it to the **Variable** field or type the name.

## Type of plot

Histogram |

A maximum of four plots can be produced at one go.

## Variable

Specifies the variate or factor that is to provide x-values for the added variable plot. This could, for example, be residuals from an analysis of variance of a possible covariate.

## Type of residual

Controls the type of residuals that are used in the plots. You can choose either **Simple** or **Standardized** residuals.

## Residuals in field layout

In a field experiment it can be useful to study the spatial pattern of the residuals, for example to see if there are any systematic trends in fertility. These options let you plot the residuals in field layout.

## Contour plot

Select this to draw a contour plot of the residuals if the plots are on a regular grid.

## Shade plot

Select this to draw a shade plot of the residuals if the plots are on a regular grid.

## Display table

Displays the residuals in a table whose structure corresponds to the field layout.

## X-coordinates

A variate specifying the X-coordinates for the locations of the plots.

## Y-coordinates

A variate specifying the Y-coordinates for the locations of the plots.

## Method

This lists the different type of residuals that can be used. Select **Combine all strata** to combine the residuals from all the strata (or error terms) in the analysis, or **Final stratum** only to use the residuals only from the final stratum.
