PROC SEQDESIGN; summarizes the options in the PROC SEQDESIGN statement. ALTREF= )>specifies the alternative reference—that is, the hypothetical reference under the alternative hypothesis at which the power is computed. The LOWER= and UPPER= options are applicable only for a two-sided design with different lower and upper alternative references.

How-To Install SAS 9.3 on Windows 7. The procedure is meant to be performed by an ITC. Statistical Analysis System language (SAS) is a statistical and matrix handling language with PL/I-like syntax. This installation is the language and its current tool set as released by the SAS Institute. The following procedure must be.

For a one-sided design, is the lower alternative reference and is the upper alternative reference. For a two-sided design, the specified and are the lower and upper alternative references, respectively. If the LOWER= option is not specified,, and if the UPPER= option is not specified,. The specification of the ALTREF= option depends on the hypothesis used in the clinical trial. For example, suppose the null hypothesis with an alternative hypothesis is used to compare two binomial populations,. Then is the proportion difference under if, and is the log odds ratio under if.

If the ALTREF= option is not specified, the alternative reference can also be specified or derived in the SAMPLESIZE statement. If is specified or derived in the SAMPLESIZE statement, and are the lower and upper alternative references, respectively. Note that if the SAMPLESIZE statement is specified with a two-sided design, the sample sizes derived by using the lower and upper alternatives might be different.

If is specified or derived in the SAMPLESIZE statement, it is used to compute the sample sizes. Otherwise, the specified in the ALTREF= option is used. BOUNDARYSCALE=MLE  SCORE  STDZ  PVALUE BSCALE=MLE  SCORE  STDZ  PVALUE specifies the scale for the statistic that is displayed in the boundary table and boundary plots. The keywords MLE, SCORE, STDZ, and PVALUE correspond to the boundary with the maximum likelihood estimate scale, the score statistic scale, the standardized normal scale, and the -value scale, respectively. The default is BOUNDARYSCALE=STDZ. With the BOUNDARYSCALE=MLE or BOUNDARYSCALE=SCORE option, the maximum information must be either explicitly specified with the MAXINFO= option or derived in the SEQDESIGN procedure to provide the necessary information level at each stage to compute the boundary values. See the section for a detailed description of the statistic scale for the boundary values.

Note that for a two-sided design, the -value scale displays the one-sided fixed-sample -value under the null hypothesis with a lower alternative hypothesis. MAXINFO= number specifies the maximum information level for the design. If the MAXINFO=option is specified and the alternative reference is either specified explicitly with the ALTREF= option or derived from the SAMPLESIZE statement, then the Type I and Type II error probability levels cannot be met simultaneously. In this case, the ALPHA= option in the DESIGN statement is applicable only with the BOUNDARYKEY=ALPHA option (which is the default) in the DESIGN statement, and the Type II error probability is derived.
