13 Description of output files 210Table of output objects and where to find them ASRemloutput object found in commentrela-mean/variancetionshipobserved variance/covariance matrixformed from BLUPsand residuals.res file.res filefor non-spatial analyses ASReml prints the slopeof the regression of log(abs(residual)) againstlog(predicted value). This regression is expectedto be near zero if the variance is independentof the mean. A power of the mean datatransformation might be indicated otherwise. Thesuggested power is approximately (1-b) where b isthe slope. A slope of 1 suggests a log transformation.This is indicative only and should notbe blindly applied. Weighted analysis or identifyingthe cause of the heterogeneity should alsobe considered. This statistic is not reliable in geneticanimal models or when units is included inthe linear model because then the predicted valueincludes some of the residual.for an interaction fitted as random effects, whenthe first [outer] dimension is smaller than the innerdimension less 10, ASReml prints an observedvariance matrix calculated from the BLUPs. Theobserved correlations are printed in the upper triangle.Since this matrix is not well scaled as an estimateof the underlying variance component matrix,a rescaled version is also printed, scaled accordingto the fitted variance parameters. Theprimary purpose for this output is to provide reasonablestarting values for fitting more complexvariance structure. The correlations may also beof interest. After a multivariate analysis, a similarmatrix is also provided, calculated from theresiduals.phenotypic variance .pvc file placed in the .pvc file when postprocessing witha .pin fileplot of residualsagainst field positiongraphics filepossible outliers .res file these are residuals that are more than 3.5 standarddeviations in magnitudepredicted (fitted) valuesat the data points.yht filethese in the are printed in the second columnpredicted values .pvs file given if a predict statement is supplied in the .asfile.REML log-likelihood .asr file the REML log-likelihood is given for each iteration.The REML log-likelihood should have converged
