Fits the second-order response surface or central composite model for continuous predictors to one or more dependent variables; a single categorical predictor (blocking factor) can also be specified. Use the General Linear Models options to specify custom designs.

**Model and
Estimation**

**Response
surface or Mixture**. Specifies whether the continuous predictors
describe standard process variables, or the components of a constrained
mixture (where the sum of component values is constant). In the latter
case, the intercept is automatically dropped from the model.

**Type of
sums of squares**. Specifies how to construct the hypotheses
for the tests of main effects and interactions, or for the continuous
predictors.

**Lack of
fit**. Requests the computation of pure error for testing the
lack-of-fit hypothesis.

**Sweep delta
1.E-**. Specifies the negative exponent for a base-10 constant
Delta (delta = 10^-sdelta); the default value is 7. Delta is used (1)
in sweeping, to detect redundant columns in the design matrix, and (2)
for evaluating the estimability of hypotheses; specifically a value of
2*delta is used for the estimability check.

**Inverse
delta 1.E-**. Specifies the negative exponent for a base-10 constant
Delta (delta = 10^-idelta); the default value is 12. Delta is used to
check for matrix singularity in matrix inversion calculations.

**Results**

**Detail of computed results reported**. Specifies the detail of
computed results reported. If All results is requested, Statistica
will also report all univariate results (for multivariate designs), descriptive
statistics, details about the design terms, the whole-model R, and the
least-squares means for all effects. Residual and predicted statistics
(for observations) can be requested as options.

**Residual analysis**. In addition to the predicted, observed, and
residual values, Statistica will compute the (default) 95%
Prediction intervals and 95% Confidence limits, the Standardized predicted
and Standardized residual score, the Leverage values, the Deleted residual
and Studentized deleted residual scores, Mahalanobis and Cook distance
scores, the DFFITS statistic, and the Standardized DFFITS statistic.

**Normal probability
plot**. Normal probability plot of residuals

**Tests homogeneity
of variances**. Tests the homogeneity of variances/covariances
assumption. One of the assumptions of univariate ANOVA is that the variances
are equal (homogeneous) across the cells of the between-groups design.
In the multivariate case (MANOVA), this assumption applies to the variance/covariance
matrix of dependent variables (and covariates).

**Plots of
means vs. std. dev**. Plots the (unweighted) marginal means (see
also the Means tab) for the selected Variables against the standard deviations.

**Generates
data source, if N for input less than**. Generates a data source
for further analyses with other Data Miner nodes if the input data source
has fewer than k observations, as specified in this edit field; note that
parameter k (number of observations) will be evaluated against the number
of observations in the input data source, not the number of valid or selected
observations.

**Deployment. **Deployment is
available if the Statistica installation is licensed for this feature.

**Generates
C/C++ code**. Generates C/C++ code for deployment of predictive
model (for a single dependent variable only).

**Generates SVB code**. Generates Statistica Visual
Basic code for deployment of predictive model (for a single dependent
variable only).

**Generates
PMML code**. Generates PMML (Predictive Models Markup Language)
code for deployment of predictive model (for a single dependent variable
only). This code can be used via the Rapid Deployment options to efficiently
compute predictions for (score) large data sets.

**Saves C/C++
code**. Save C/C++ code for deployment of predictive model (for
a single dependent variable only).

**File name
for C/C code**. Specify the name and location of the file where
to save the (C/C++) deployment code information.

**Saves SVB code**. Save Statistica Visual Basic code
for deployment of predictive model (for a single dependent variable only).

**File name
for SVB code**. Specify the name and location of the file where
to save the (SVB/VB) deployment code information.

**Saves PMML
code**. Saves PMML (Predictive Models Markup Language) code for
deployment of predictive model (for a single dependent variable only).
This code can be used via the Rapid Deployment options to efficiently
compute predictions for (score) large data sets.

**File name
for PMML (XML) code**. Specify the name and location of the file
where to save the (PMML/XML) deployment code information.
