I am working with the NHANES 2011-2018 data and I am trying to exclude the "Don't Know", "Refused", and missing responses from the analysis. Following the suggestions in this thread, I created a variable, ANALYSIS for the observations I wanted to include in my analysis: DATA data.DSdec_cd; SET data.DSdec; KEEP RIAGENDR RIDAGEYR DMDYRSUS DMDEDUC2 INDFMPIR ACD040 SDMVSTRA SDMVPSU WTINT10YR FSDHH ANALYSIS; IF (DMDYRSUS IN (1:9) AND DMDEDUC2 IN (1:5) AND INDFMPIR ge 0 AND ACD040 IN (1:5) AND FSDHH IN (1:4)) THEN ANALYSIS = 1; ELSE ANALYSIS = 0; RUN; However, the following SURVEYLOGISTIC procedure: PROC SURVEYLOGISTIC data = data.DSdec_cd order = data NOMCAR; DOMAIN ANALYSIS ("1"); STRATA SDMVSTRA; CLUSTER SDMVPSU; WEIGHT WTINT10YR; CLASS RIAGENDR (REF = LAST) DMDYRSUS (REF = FIRST) DMDEDUC2 (REF = FIRST) ACD040 (REF = FIRST) FSDHH (REF = FIRST) / PARAM = REF; MODEL FSDHH = RIAGENDR RIDAGEYR ACD040 / CLODDS; ODS SELECT Domain2.CLOdds; RUN; It still includes the "Don't Know" (7) and "Refused" (9) categories. I don't understand why they are still included or if it's possible to exclude them from the analysis or at least the output. I've used WHERE statements to subset the data, but I understand that that is not the way to restrict the analysis to a subset of the data.   I am also wondering how to get Wald confidence limits with SURVEYLOGISTIC,  as the documentation say that I can but does not do by default.   ...

I am a public health graduate student working with the NHANES data set. I'm trying to use SURVEYLOGISTIC to create a risk ratio plot with confidence limits. The professor provided the following code snippet:   ods graphics on; proc logistic data= NH1720_A; class stroke (ref=first) SMKGP (REF=FIRST) racegp4 (ref=first) EDUGP4 (REF=LAST) / param=ref; model STROKE = Age sex racegp4 EDUGP4 SMKGP / risklimits; run; ods graphics off; It outputs the plot as expected.   When I run the following code:  ODS GRAPHICS ON; PROC SURVEYLOGISTIC data = analysis.DSdec NOMCAR; STRATA SDMVSTRA; CLUSTER SDMVPSU; WEIGHT WTINT10YR; CLASS RIAGENDR (REF = LAST) DMDYRSUS (REF = FIRST) DMDEDUC2 (REF = FIRST) ACD040 (REF = FIRST) FSDHH (REF = FIRST) / PARAM = REF; MODEL FSDHH (EVENT = "High") = RIAGENDR RIDAGEYR DMDYRSUS DMDEDUC2 INDFMPIR ACD040 / CLODDS RISKLIMITS; LABEL RIAGENDR = "Gender" RIDAGEYR = "Age" DMDYRSUS = "Years of Residency in US" DMDEDUC2 = "Highest Educational Level Attained" INDFMPIR = "Ratio of Income to Federal Poverty Level" FSDHH = "Household Food Security"; FORMAT RIAGENDR genderCatF. DMDYRSUS USResLenCatF. DMDEDUC2 eduCatF. ACD040 homeLangCatF. FSDHH HHFoodSecCatF.; RUN; ODS GRAPHICS OFF; I get the following errors: ERROR 22-322: Syntax error, expecting one of the following: ;, ABSFCONV, ALPHA, CHISQ, CLODDS, CLPARM, CODING, CORRB, COVB, DF, EXPB, FCONV, GCONV, GRADIENT, ITPRINT, L, LINK, MAXITER, NOCHECK, NODUMMYPRINT, NOINT, OFFSET, PARMLABEL, RIDGING, RSQUARE, SINGULAR, STB, TECH, TECHNIQUE, VADJUST, XCONV. ERROR 202-322: The option or parameter is not recognized and will be ignored. Also, the syntax colorer in SAS Studio 3.81 colors the RISKLIMITS options in the professor's code, but not in mine, and removing the NOMCAR option in my code does not resolve the error.  ... View more
