Summary of Features
SAS/INSIGHT software provides a comprehensive set of
exploratory and analytical tools.
To explore data, you can
- identify observations in plots
- brush observations in linked scatter plots, histograms,
box plots, line plots, contour plots, and three-dimensional rotating plots
- exclude observations from graphs and analyses
- search, sort, and edit data
- transform variables
- color observations based on the value of a variable
To analyze distributions, you can
- compute descriptive statistics
- create quantile-quantile plots
- create mosaic plots of cross-classified data
- fit parametric (normal, lognormal, exponential, Weibull)
and kernel density estimates for distributions
- fit parametric and empirical cumulative distribution functions
- test hypotheses of completely specified (known parameters)
or specific (unknown parameters) parametric distributions
based on Kolmogorov's D statistic
To analyze relationships between a response variable and a set of
explanatory variables, you can
- fit curves with polynomials, kernels, and smoothing splines
- fit curves with nonparametric local polynomial smoothers
using either a fixed bandwidth or loess smoothing
- add confidence bands for mean and predicted values
- fit surfaces with polynomials, kernels, and smoothing splines
- create residual and leverage plots
- fit the general linear model, including classification effects
for analysis of variance and analysis of covariance
- fit the generalized linear model, including
logistic regression, Poisson regression, and other models
To analyze relationships between variables, you can
- calculate correlation matrices and scatter plot matrices with
confidence ellipses for relationships among pairs of variables
- reduce dimensionality of interval variables with
principal component analysis
- examine relationships between two sets of interval variables
with canonical correlation analysis and maximum redundancy analysis
- examine relationships between a nominal variable and a set
of interval variables with canonical discriminant analysis
In addition, you can
- process data by groups
- process multiple data sets
- store option settings to customize SAS/INSIGHT operation
- store results as SAS data sets, SAS/GRAPH catalogs,
and text files
- record and submit SAS/INSIGHT statements
- obtain context-sensitive help
Finally, because it is a part of the SAS System,
you can use SAS/INSIGHT software to explore results
from any SAS procedure. Conversely, you can use any SAS procedure
to analyze results from SAS/INSIGHT software.
