你使用的命令不需要这么多的变量。所以会出现上述提示。或者你变量位置写错了。
将数据输入Stata的数据编辑窗口,或复制Excel表格的数据粘贴到数据编辑窗口,合并效应值需要用到以下数据:OR、RR、HR及其95%CI。如下图所示,录入相关数据(lci、uci分别为95%CI的下限和上限)。 2、数据转换 对rr、lci、uci取对数: gen logrr=log(rr); gen loglci=log(lci); gen loguci=log(uci)。 3、得到...
STATA导出EXCEL时提示导出too many or no variables specified 导出XLSX格式。 如果选择xls格式行数有限
想问下解决了吗

2. set obs n to make a dataset of n observations on no variables; if n were 100, we would type set obs 100. 3. gen x = ( n-1)/(n-1)*(b-a)+a because the built-in variable n is 1 in the first observation, 2 in the second, and so on; see [U] 13.4 System variables...
