Macro Usage

robertrao — Sat, 13 Oct 2012 01:25:31 GMT

Hi Team,

I have a Macro but I am not knowing how to use it in this kind of situation.

The difference I am not getting is that how can I get Means side by side for example: type b type h and typec

i am able to get the result if any one variable is present but here three variables are side by side for which we have to produce Means and freqs..

I will post the code

Also how do I get the Total variable twiceone is a subtotal and the other is a grand total

THANKS

Type(b/h) Total typec TOTAL

b h

Age, years n=? n=? n= ? n=? n=?

Mean (SD) 46(13) 34(5)

Median

Min-Max 13-45 45-60

BMI

Mean (SD)

Median

Min-Max

Diabetes

Smoking

current 40(40%) 60(60%)

Former 60(60%) 40(40%)

Gender

Male

Female

HTN

yes

Here is the code:

This macro creates a table of
charateristics for the variables listed.

It handles categorical, binary and continuous variables and produces and output
dataset that can be further customized. No statistical information is

included in this analysis

*/

/*Parameters to be set:

dsetin - name of dataset to be analyzed

cont = macro variable list of variable names, ie cont=age weight height

cat=list of categorical variables ie cat=sex grade

bin=binary variables, such as smoking now, smoking ever

dsetout=name of output dataset

Run example at the end for a
sample output dataset call sample_table_char in the work directory.

Based on the user formatting the variables the way the results should be and
with appropriate labels for variable names.

HI Team

b h and c types are under the same variable

DO I need to subset b and c first with a where condition and use a class stmnt in the proc means and another proc means separately for typec? And merge themm both

AM confused

THanks
