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 residual.plots Residual plots for a linear model. panel.cartesian trellis panel function, with labeled rows and columns and without strip labels. do.formula.trellis.xysplom Interprets model formulas for xysplom and extended bwplots norm.curve plot a normal or a t-curve with both x and z axes. 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. arma.loop Loop through a series of ARIMA models and display coordinated tables and diagnoastic graphs. ae.dotplot AE (Adverse Events) dotplot of incidence and relative risk HH-package Support software for Statistical Analysis and Data Display by Richard M. Heiberger and Burt Holland plot.multicomp Multiple comparisons plot that gives independent user control over the appearance of the significant and not significant comparisons. extra Miscellaneous functions that I wish were in or consistent between S-Plus and R. intxplot Interaction plot, with an option to print standard error bars. arima.diag.hh Repair design error in S-Plus arima.diag panel.ci.plot Default Panel Function for ci.plot grid.yaxis.hh make x- and y-axis labels strip.background0 Turn off the coloring in the trellis strip labels. Color 0 is the background color. seqplot Time series plot. interaction2wt Plot all main effects and twoway interactions in a multifactor design panel.dotplot.tb Dotplot with evenly spaced tiebreakers. odds.ratio Calculate or plot the odds ratio for a 2x2 table of counts. bwplot.formula Replacement for bwplot.formula and compute.packet in R to allow them to work with the new "positioned" class. aov.sufficient Analysis of variance from sufficient statistics for groups. glht.mcp.993 Retain averaging behavior that was previously available in glht. ancova Compute and plot oneway analysis of covariance HH_regsubsets Display tabular results for Best Subsets Regression. X.residuals Residuals from the regression of each column of a data.frame against all the other columns. plot.hov Homogeneity of Variance Plot hh Resolve filenames relative to the HH directory. print.tsdiagplot Print a "tsdiagplot" object. panel.pairs.hh Function based on S-Plus panel.pairs to add the subpanel.scales and panel.cex arguments. gof.calculation Calculate Box--Ljung Goodness of Fit for ARIMA models in S-Plus. orthog.complete Construct an orthogonal matrix which is an arbitrary completion of the column space of the input set of columns. panel.xysplom panel method for xysplom. anova.mean ANOVA table from the group sample sizes, means, and standard deviations. panel.bwplot.intermediate.hh Panel functions for bwplot. hov Homogeneity of Variance ci.plot Plot confidence and prediction intervals for simple linear regression summary.arma.loop summary and print and subscript methods for tsdiagplot and related objects. panel.interaction2wt Plot all main effects and twoway interactions in a multifactor design lmatRows Find the row numbers in the lmat corresponding to the focus factor. multicomp.reverse Force all comparisons in a "multicomp" object to have the same sign. ancova-class Class "ancova" Analysis of Covariance diag.maybe.null Returns a value for the diagonal of NA and NULL arguments. positioned-class Class "positioned", extends "ordered" to specify the position for graphing the levels of a factor. ladder Draw a "ladder of powers" plot, plotting each of several powers of y against the same powers of x. multicomp.order Update a multicomp object by ordering its contrasts. panel.acf Panel functions for tsdiagplot. tsacfplots Coordinated time series and ACF and PCF plots. regr1.plot plot x and y, with optional straight line fit and display of squared residuals xysplom scatterplot matrix with potentially different sets of variables on the rows and columns. position Find or assign the implied position for graphing the levels of a factor.
