Interactive Data Exploration
SAS/INSIGHT software, a component of the SAS System, is a dynamic tool for exploring and analyzing your data. With it you can examine univariate distributions, visualize multivariate data, and fit models using regression, analysis of variance, and the generalized linear model.
With SAS/INSIGHT software, all graphs and analyses are dynamic. Spin a three-dimensional plot to explore your data. Click on points to identify them. Add and remove model effects as fast as you can evaluate them.
All graphs and analyses are linked. Brush observations in one window and they are highlighted in all windows. Color a point in one graph and it receives the same color in all displays. Exclude an observation from calculations, and all analyses recalculate automatically.
Dynamically linked graphs and analyses make it easy to find patterns in your data. Once a pattern is spotted, powerful modeling facilities enable you to quickly build models and analyze relationships.
Explore Your Data Easily
SAS/INSIGHT software displays SAS data sets in tabular form. Use the data window to enter new data values, sort and search the data, extract subsets, and open as many data sets as you like. Point and click to create exploratory graphics including box plots, histograms, scatter plots, mosaic plots, overlaid line plots, and 3-D rotating plots.
Compute descriptive statistics and correlations to confirm numerically the relationships you find visually. For high-dimensional data, plot principal components in two or three dimensions to understand the structure of your data.
Find the Best Model Quickly
When you have identified potential relationships in your data, test your ideas with powerful modeling facilities. Fit polynomial curves with confidence bands, kernel estimates, smoothing splines, and loess smoothers. All curves are dynamically adjustable with slider controls.
Fit linear models with classification effects for analysis of variance and analysis of covariance. Choose response distributions and link functions to fit logistic regression. Poisson regression, and other generalized linear models. With a few keystrokes you can add and remove model effects--quickly creating as many models as you like.
Check Model Assumptions Efficiently
Evaluate your models using summary statistics, analysis of variance, parameter estimates, and collinearity diagnostics. Create residual-by-predicted plots to diagnose nonconstant error variance and identify outliers. Use partial leverage plots to examine changes in the residuals for the model with and without each explanatory variable.
To detect influential observations, plot influence diagnostic variables including hat diagonal, standardized and studentized residuals, Cook's D, Dffits, Covratio, and Dfbetas. To check distribution of residuals, create dynamic histograms, box plots, quantile-quantile, and CDF plots. Test for normal, lognormal, exponential, and Weibull distributions using Kolmogorov's D statistic.
Put SAS/INSIGHT Software to the Test
Because SAS/INSIGHT software is a component of the SAS System, you can use it to explore output from any SAS procedure--and you can use any SAS procedure to analyze results from SAS/INSIGHT software. Use grammar statements to keep records of your work--or to analyze results from other SAS System components.
Dynamic graphics, advanced modelling, and integration with the SAS System make SAS/INSIGHT software a powerful tool for data analysis. The easily learned, point-and-click interface enables you to achieve results quickly.
