New Statistix 9 Upgrade Now Available

We’re proud to present our very latest version of Statistix. Released in January 2008, new Statistix 9 now meets your needs more than ever with new and improved procedures and additional features.

This latest version boasts a completely new Nonlinear Models menu featuring Nonlinear Regression, Polynomial Regression, Loess (locally weighted regression), and Spline Interpolation.

You’ll also enjoy many new procedures such as Dot Plot, Scatter Plot Matrix, Coplot, Contour Plot, Quantile Plot, and Q-Q Plot.

Many existing procedures have been enhanced with additional options:

  • Residual plots: Add loess curves to detect trends.
  • Histograms: Juxtaposed charts for easy comparison.
  • Regression: Added pure error, PRESS, and Akaike’s Information Criterion.
  • Scatter Plot: Added loess and connect points options.
  • Random function: Added beta, binomial, chi-square, exponential, F, gamma, Poisson distributions plus random permutations.
  • Chi-square Test: Added multiple comparisons for proportions in 2 × c contingency tables.
  • Multiple comparison support for multiple error term AOV models including split-plot and strip-plot models.
  • Vista compatible HTML style help file.

Nonlinear Regression
  • Models allow for up to 20 parameters and 20 independent variables.
  • 30 predefined models for easy specification and automatic starting values.
  • Specify your own models using 13 built-in functions.
  • Marquardt algorithm with numerical derivatives.
  • Parameter estimates include standard errors and confidence intervals.
  • Save fitted values, confidence intervals, and residuals in new variables.
  • Correlation and variance-covariance matrices.
  • Akaike’s Information Criterion for model comparisons.
  • Easily generate fitted curves, contour plots, surface coplots, and residuals plots.

Loess - Locally Weighted Regression
  • Fit curves and surfaces to multi-dimensional data.
  • Specify models with up to 5 independent variables.
  • Fit models using linear and/or quadratic polynomials.
  • Robust estimation for symmetric error distributions.
  • Built-in coplots of fitted surfaces and residuals for easy evaluation of interactions between variables.
  • Contour plots for models with two independent variables.
  • Save fitted values, confidence intervals, and residuals.
  • AOV for comparison of nested models.

Polynomial Regression
  • Specify models up to degree 9.
  • Automatically fits interaction terms for models with more than one variable.
  • Extensive residual analysis options.
  • Easily generate fitted curves, contour plots, surface coplots, and residuals plots.
  • Variance-covariance matrix of coefficients.

Here are even more good reasons to upgrade now.
  • Coplots (conditioning plots) graphically depict conditional dependence. A matrix of bivariate scatter plots are displayed conditioned on one or two factors. It is a powerful method for studying how a response variable depends on two or more factors.
  • Expanded graphical capabilities for comparing distributions of two or more samples. Now you can plot juxtaposed histograms using a common scale. Quantile plots and Q-Q plots are powerful methods for comparing distributions.
  • The new scatter plot matrix makes it easy to evaluate the relationships among several variables on a single plot. Rows and columns of plots share the same scale.
  • The new dot plots convey quantitative data better than bar charts and pie charts. Options include superimposed and juxtaposed plots for between-group comparisons.
