1 MULTI-WAY TABLES IN REPORT

2 Consider The following PROC REPORT: proc format; value smk 0='Never Smoked' 1='Currently Smoke' 2='Stopped at Pregnancy' 3='Stopped Before Current Pregnancy' 9='Unknown' ; value gest low-<259='premature' 259-<999='Normal' 999='Unknown' ; options nodate nonumber; Title 'Birthweight Summaries'; proc report data=mysas.birthweight nowd headline headskip; where smoke ne 9 and gestation lt 999; column smoke gestation birth_wt; define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. 'Delivery' group; define birth_wt/ n width=15 'Number'; break after smoke/summarize skip suppress ol;

4 Two-Way Table Suppose I wanted to display the birth status across two columns I can achieve this by specifying that the birth_wt variable be nested under gestation (using the comma as an operator) which is displayed using the across option in its define statement: proc report data=mysas.birthweight nowd headline headskip; where smoke ne 9 and gestation lt 999; column smoke gestation,birth_wt; define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. '_Delivery_/ ' across; define birth_wt/ n width=15 ' ';

5 Two-Way Table Suppose I wanted to display the birth status across two columns I can achieve this by specifying that the birth_wt variable be nested under gestation (using the comma as an operator) which is displayed using the across option in its define statement: proc report data=mysas.birthweight nowd headline headskip; where smoke ne 9 and gestation lt 999; column smoke gestation,birth_wt; define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. '_Delivery_/ ' across; define birth_wt/ n width=15 ' '; The / operator in a label forces a line break. The _ at either end inserts a spanning line

7 Additions Suppose I want a column summary for each as a final row in the table. RBREAK will still give a full report summary, so add: rbreak after/summarize ol; To get:

9 More Additions Suppose I want row totals as an extra column in the table. Consider these modifications: proc report data=mysas.birthweight nowd headline; where smoke ne 9 and gestation lt 999; column smoke gestation,birth_wt birth_wt=num; define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. '_Delivery_/' across; define birth_wt/ n width=15 ' '; define num/n 'Total'; rbreak after/summarize ol;

10 More Additions Suppose I want row totals as an extra column in the table. Consider these modifications: proc report data=mysas.birthweight nowd headline; where smoke ne 9 and gestation lt 999; column smoke gestation,birth_wt birth_wt=num; define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. '_Delivery_/' across; define birth_wt/ n width=15 ' '; define num/n 'Total'; rbreak after/summarize ol; Add a column and give it an appropriate definition.

11 Result This is not directly totaling in each row, it is an independent column definition that happens to do what we want...

12 Multiple Statistic Columns It is possible to display multiple statistics in the across format. Consider: options nodate nonumber ls=140; Title 'Birthweight Summaries'; proc report data=mysas.birthweight nowd headline; where smoke ne 9 and gestation lt 999; column smoke gestation,(birth_wt=num birth_wt=avg birth_wt=med birth_wt=sd); define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. '_Delivery Status_/ ' across; define num/ n 'N'; define avg/ mean 'Mean' format=10.1; define med/ median 'Median' format=10.1; define sd/ std 'Std. Deviation' format=10.1;

Consider: options nodate nonumber ls=140; Title 'Birthweight Summaries'; proc report data=mysas.birthweight nowd headline; where smoke ne 9 and gestation lt 999; column smoke gestation,(birth_wt=num birth_wt=avg birth_wt=med birth_wt=sd); define smoke/format=smk. 'Smoking Status' group order=internal; define gestation/format=gest. '_Delivery Status_/ ' across; define num/ n 'N'; define avg/ mean 'Mean' format=10.1; define med/ median 'Median' format=10.1; define sd/ std 'Std. Deviation' format=10.1; Nest the statistics you want (note aliasing) with parentheses and the comma operator.

'_Delivery Status_/ ' across; define num/ n 'N'; define avg/ mean 'Mean' format=10.1; define med/ median 'Median' format=10.1; define sd/ std 'Std. Deviation' format=10.1; Put in proper definitions for the stats you want.

16 Larger Tables Consider the following report: proc format; value lake 1='Oligotrophic' 2='Eutrophic' 3='Mesotrophic' ; value dam 0='No' 1='Yes' ; value merc low-<.5='acceptable'.5-1='dangerous' 1<-high='Toxic' ; options ls=120 nonumber nodate; Title 'Median Elevations'; proc report data=mysas.fish nowd headline; column lt hg dam elv; define lt/ format=lake. group; define dam/format=dam. group width=8; define hg/ format=merc. group 'Mercury Level'; define elv/ median 'Median Elevation' format=9.1; break after lt/summarize skip suppress ol; break after hg/skip ;

18 Convert a Group Variable to Columns Let s put the dam variable across the columns: proc report data=mysas.fish nowd headline; column lt hg dam,elv; define lt/ format=lake. group; define dam/format=dam. across width=8 '_Dam_/ ' ; define hg/ format=merc. group 'Mercury Level'; define elv/ median '' format=9.1; break after lt/summarize skip suppress ol;
