## Statistical Analysis and Data Display: Heiberger and Holland

Support software for Statistical Analysis and Data Display (Springer, ISBN 0-387-40270-5). This contemporary presentation of statistical methods features extensive use of graphical displays for exploring data and for displaying the analysis. The authors demonstrate how to analyze data---showing code, graphics, and accompanying computer listings---for all the methods they cover. They emphasize how to construct and interpret graphs, discuss principles of graphical design, and show how accompanying traditional tabular results are used to confirm the visual impressions derived directly from the graphs. Many of the graphical formats are novel and appear here for the first time in print. All chapters have exercises.

## Functions in HH

 Name Description anova.mean ANOVA table from the group sample sizes, means, and standard deviations. panel.ci.plot Default Panel Function for ci.plot X.residuals Residuals from the regression of each column of a data.frame against all the other columns. arma.loop Loop through a series of ARIMA models and display coordinated tables and diagnoastic graphs. extra Miscellaneous functions that I wish were in or consistent between S-Plus and R. F.curve plot a chisquare or a F-curve. hh Resolve filenames relative to the HH directory. panel.interaction2wt Plot all main effects and twoway interactions in a multifactor design panel.bwplott Extension to S-Plus trellis to allow transposed plots. col.hh Initializing Trellis Displays regr2.plot 3D plot of z against x and y, with regression plane fit and display of squared residuals. axis.i2wt specialized axis function for interaction2wt. xysplom scatterplot matrix with potentially different sets of variables on the rows and columns. objip loop through all attached directories looking for pattern mmc.mean MMC (mean--mean multiple comparisons) plots from the sufficient statistics for a one-way design. panel.dotplot.tb Dotplot with evenly spaced tiebreakers. orthog.complete Construct an orthogonal matrix which is an arbitrary completion of the column space of the input set of columns. push.vp.hh push and pop a grid viewport, turn clipping off, change scale. panel.cartesian trellis panel function, with labeled rows and columns and without strip labels. multicomp.reverse Force all comparisons in a "multicomp" object to have the same sign. if.R Conditional Execution for R or S-Plus interaction.positioned interaction method for positioned factors. resid.squares plot squared residuals in inches to match the y-dimension GSremove Remove selected GraphSheetPages in the S-Plus Windows GUI Graphsheet sufficient Calculates the mean, standard deviation, and number of observations in each group of a data.frame that has one continuous variable and two factors. grid.yaxis.hh make x- and y-axis labels panel.acf Panel functions for tsdiagplot. dchisq.intermediate Intermediate f and chisq functions to simplify writing for both R and S-Plus. ci.plot Plot confidence and prediction intervals for simple linear regression partial.corr partial correlations as.multicomp Support functions in R for MMC (mean--mean multiple comparisons) plots. mmc MMC (mean--mean multiple comparisons) plots. legendGrob2wt place separate keys to the left of each row of a trellis t.trellis Interchange the x- and y-axes for an S-Plus trellis object. Interchange the conditioning variables for an R trellis object. ae.dotplot AE (Adverse Events) dotplot of incidence and relative risk do.formula.trellis.xysplom Interprets model formulas for xysplom and extended bwplots intxplot Interaction plot, with an option to print standard error bars. HH-package Support software for Statistical Analysis and Data Display by Richard M. Heiberger and Burt Holland seqplot.forecast seqplot with confidence bands for the forecast region. hov Homogeneity of Variance multicomp.order Update a multicomp object by ordering its contrasts. gof.calculation Calculate Box--Ljung Goodness of Fit for ARIMA models in S-Plus. position Find or assign the implied position for graphing the levels of a factor. A new class "positioned", which inherits from "ordered" and "factor", is defined. persp.plane Helper functions for regr2.plot aov.sufficient Analysis of variance from sufficient statistics for groups. ladder Draw a "ladder of powers" plot, plotting each of several powers of y against the same powers of x. strip.xysplom strip function that is able to place the correlation or regression coefficient into the strip label. strip.background0 Turn off the coloring in the trellis strip labels.
