发帖数: 336 | 1 需要在proc IML里用一个 1 到3000000的do loop。
每个loop里要给一个15000000*1的vector的几个element赋值。
跑一次要挺长时间。问题是这个loop是用来算loglikelihood的，
要被下面optimize的routine 反复的call。请教大家怎么能让
这个do loop快一些。
在R里有sapply之类可以替代for loop，算起来快无数倍,sas里有
sapply这样的function么？
code如下：
proc IML;
/* write the log-likelihood function*/
start LogLik(param) global (datain);
igrp = datain[,5];*datain[,5] is group id
X = datain[,1:4]; *datain[,1:4] are independent variables
expXb = exp(X*param);
uniqIgrp = unique(igrp)`;
sumExpXb = ... 阅读全帖 |

发帖数: 305 | 3 这个用ods regions 的xy选项就可以实现啊！
example
ods layout start;
ods region x=0 in y=5.5 in height=4 in width=4 in;
%bar_chart(&dataIn, %scan(&varList,&i.,' '));
ods region x=4 in y=5.5 in height=4 in width=4 in;
%pie_chart(&dataIn, %scan(&varList,&i.,' '));
ods layout end; |
