The PROC SEQTEST statement invokes the SEQTEST procedure. Table 84.1 summarizes the options available in the PROC SEQTEST statement.

Description 

Input Data Sets 

Specifies the data set for boundary information 

Specifies the data set for parameter estimates and information levels 

Specifies the data set for parameter estimates and standard errors 

Boundaries 

Specifies whether the boundary is used in the computation 

of the Type I error level 

Checks for overlapping of the lower and upper boundaries 

at the current and subsequent interim stages in a twosided design 

Specifies the boundary key to maintain Type I and II error probability levels 

Specifies the boundary scale 

Specifies error spending methods for boundary adjustments 

Specifies minimum error spending values for the boundaries 

Specifies whether information levels at future interim stages should be 

adjusted 

Specifies the number of stages 

Test Statistics 

Specifies the test variable in the DATA= data set 

Specifies the test variable in the PARMS= data set 

pValues and Confidence Intervals 

Specifies the significance levels for the confidence interval 

Specifies the types of confidence interval 

Specifies the ordering of the sample space used to derive 

the pvalues and confidence limits 

Table Output 

Displays conditional powers 

Displays the cumulative error spending at each stage 

Displays the predictive powers 

Displays the powers and expected sample sizes 

Displays the repeated confidence intervals 

Displays the expected cumulative stopping probabilities 

Graphics Output 

Displays the expected sample numbers plot 

Displays the conditional powers plot 

Displays the error spending plot 

Displays the powers plot

The BOUNDARY= option provides the information for the design and is required in the PROC SEQTEST statement. By default, the SEQTEST procedure displays tables of design information and test information. If ODS Graphics is enabled, the procedure also displays a sequential test plot.
