Nevertheless, here is how to work around the limitation in the old version ofreshape: Step 1. Create demogs.dta containing the demographic variables. . useyourdata. keep id sex age race hgt wgt shoesize hatsize ms kids addr. sort id. quietly by id: keep if _n==1. save demogs, rep...
reshapemoves back and forth between what Stata calls wide data structures and long data structures. In a wide structure, rectangular blocks of data are held in several variables (i.e., several columns), whereas in a long data structure, such blocks are stretched out into single variables (one...

Faster Stata for Big Data This package provides a fast implementation of various Stata commands using hashes and C plugins. The syntax and purpose is largely analogous to their Stata counterparts; for example, you can replacecollapsewithgcollapse,reshapewithgreshape, and so on. For a comprehensive...
因为我们没有在命令中指定性别,所以Stata假定它在逻辑观察中是恒定的,这里是id。 Wide and long data forms 将数据视为样本Xij的集合,其中i是逻辑观察或组标识符,j是子观察或组内标识符。通过逻辑观察来组织宽格式数据,将所有数据存储在一行中的特定观察上。 通过子观察组织长格式数据,将数据存储在多行中。
