Thus,assume the variance structure is modelled with reduced parameters,if that modelled structure is then processed as theinitial values of a US structure, ASReml tests the adequacyof the reduced parameterization.causes ASReml to report a general description of the distributionof the data variables and factors and simple correlationsamong the variables for those records included in the analysis.This summary will ignore data records for which thevariable being analysed is missing unless a multivariate analysisis requested or missing values are being estimated. Theinformation is written to the .ass file.!X v !Y v !G v !JOIN is used to plot the (transformed) data. Use !X to specifythe x variable, !Y to specify the y variable and !G to specifya grouping variable. !JOIN joins the points when the xvalue increases between consecutive records. The groupingvariable may be omitted for a simple scatter plot. Omit !Yy produce a histogram of the x variable.For example,!X age !Y height !G sexNote that the graphs are only produced in the graphics versionsof ASReml (Section 12.3).For multivariate repeated measures data, ASReml can plotthe response profiles if the first response is nominated withthe !Y qualifier and the following analysis is of the multivariatedata. ASReml assumes the response variables are incontiguous fields and are equally spaced.
