我正在学习 SAS 中的 drop_conditions。我要求提供三个变量的样本,但只检索到两个观察值。请指教!谢谢!
data temp;
set mydata.ames_housing_data;
format drop condition $30.;
if (LotArea in (7000:9000)) then drop_condition = '01: Between 7000-9000 sqft';
else if (LotShape EQ 'IR3') then drop_condition = '02: Irregular Shape of Property';
else if (condition1 in 'Artery' OR 'Feedr') then drop_condition = '03: Proximity to arterial/feeder ST';
run;
proc freq data=temp;
tables drop_condition;
title 'Sample Waterfall';
run; quit;
