ESTIMATE Statement

< / options>
;

The ESTIMATE statement provides a mechanism for obtaining custom hypothesis tests. Estimates are formed as linear estimable functions of the form . You can perform hypothesis tests for the estimable functions, construct confidence limits, and obtain specific nonlinear transformations.

Table 88.4 summarizes important options in the ESTIMATE statement.

Table 88.4 Important ESTIMATE Statement Options

Option

Description

Construction and Computation of Estimable Functions

DIVISOR=

Specifies a list of values to divide the coefficients

NOFILL

Suppresses the automatic fill-in of coefficients for higher-order effects

SINGULAR=

Tunes the estimability checking difference

Degrees of Freedom and p-values

ADJUST=

Determines the method for multiple comparison adjustment of estimates

ALPHA=

Determines the confidence level ()

LOWER

Performs one-sided, lower-tailed inference

STEPDOWN

Adjusts multiplicity-corrected p-values further in a step-down fashion

TESTVALUE=

Specifies values under the null hypothesis for tests

UPPER

Performs one-sided, upper-tailed inference

Statistical Output

CL

Constructs confidence limits

CORR

Displays the correlation matrix of estimates

COV

Displays the covariance matrix of estimates

E

Prints the matrix

JOINT

Produces a joint or chi-square test for the estimable functions

SEED=

Specifies the seed for computations that depend on random numbers
