我用reshpe进行数据转置,结果却显示这样
values of variable year not unique within hhcode
Your data are currently long. You are performing a reshape wide. You
specified i(hhcode) and j(year). There are observations within i(hhcode)
with the same value of j(year). In the long data, variables i() and j()
together must uniquely identify the observations.
但是我的年份和我的身份代码是一一对应的,结果还是不成功
