You can specify the level (for which to compute the binomial proportion) by using the BINOMIAL(LEVEL=) option in the PROC FREQ TABLES statement. For example, tables Response / binomial(level='yes'); ... View more

Are you asking how PROC FREQ computes the exact confidence limits for the binomial proportion? This computation is documented here: Binomial Proportion: Exact (Clopper-Pearson) Confidence Limits  When the observed proportion is 1, the upper confidence limit is set to 1, and the lower limit is computed as described for P_L.       ...

There are some examples of how to customize PROC FREQ plots in this paper by Kathryn McLawhorn: "Tables and Graphics that will FREQ You Out" . See pages 19-20 for how to change titles and axis labels in PROC FREQ plots.   Some documentation is here: Statistical Graphics Using ODS: Modifying Your Graphs  ODS Graphics Template Modification  Examples of ODS Graphics Template Modification      ...

The CHISQ option in the TABLES statement (in PROC FREQ) produces several chi-square tests and measures, which include the continuity-adjusted chi-square for 2x2 tables. You don't need to specify a separate/additional option to request the continuity-adjusted chi-square.   PROC FREQ computes the continuity-adjusted chi-square by using the Yates (1934) correction. For details, see the subsection "Continuity-Adjusted Chi-Square Test" in the section Chi-Square Tests and Statistics.    This correction (Yates 1934) was developed to improve the chi-square approximation for 2x2 contingency tables in which the sample sizes (cell expected frequencies) are small. Generally speaking, continuity corrections are not heavily used these days for contingency tables because exact tests are now available.    For 2x2 tables, Fisher's exact test is automatically produced by the CHISQ option. For larger tables, you can request Fisher's exact test (and other exact chi-square tests) by using the EXACT statement.   Hope this helps.    ... View more
