## 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 arma.loop Loop through a series of ARIMA models and display coordinated tables and diagnoastic graphs. diag.maybe.null Returns a value for the diagonal of NA and NULL arguments. grid.yaxis.hh make x- and y-axis labels col.hh Initializing Trellis Displays dchisq.intermediate Intermediate f and chisq functions to simplify writing for both R and S-Plus. panel.bwplott Extension to S-Plus trellis to allow transposed plots. cp.calc Rearranges and improves the legibility of the output from the stepwise function in S-Plus. F.curve plot a chisquare or a F-curve. ae.dotplot AE (Adverse Events) dotplot of incidence and relative risk X.residuals Residuals from the regression of each column of a data.frame against all the other columns. gof.calculation Calculate Box--Ljung Goodness of Fit for ARIMA models in S-Plus. interaction.positioned interaction method for positioned factors. mmc.mean MMC (mean--mean multiple comparisons) plots from the sufficient statistics for a one-way design. multicomp.order Update a multicomp object by ordering its contrasts. push.vp.hh push and pop a grid viewport, turn clipping off, change scale. axis.i2wt specialized axis function for interaction2wt. tsdiagplot Times series diagnostic plots for a structured set of ARIMA models. panel.interaction2wt Plot all main effects and twoway interactions in a multifactor design resid.squares plot squared residuals in inches to match the y-dimension positioned-class Class "positioned", extends "ordered" to specify the position for graphing the levels of a factor. summary.arma.loop summary and print and subscript methods for tsdiagplot and related objects. partial.corr partial correlations ladder Draw a "ladder of powers" plot, plotting each of several powers of y against the same powers of x. ancova-class Class "ancova" Analysis of Covariance panel.cartesian trellis panel function, with labeled rows and columns and without strip labels. seqplot.forecast seqplot with confidence bands for the forecast region. print.tsdiagplot Print a "tsdiagplot" object. lm.case case statistics for regression analysis norm.curve plot a normal or a t-curve with both x and z axes. plot.mmc.multicomp MMC (Mean--mean Multiple Comparisons) plot. hh Resolve filenames relative to the HH directory. panel.acf Panel functions for tsdiagplot.
