初级部分 Lecture 1 Using directories to organize your work Lecture 2 1. Working with data Lecture 3 In this lecture we're going to talk about getting data into Stata. I'm not going to talk about input and edit because they are easy enough for you to master on your own. I want to talk about reading data from a disk. Lecture 4 In this lecture, we wrap things up with data organization. Stata has several ways to merge and append data, and yes, there is a difference. Merged data has been joined "side by side", whereas appended data is joined "top to bottom". 中级部分 Table of contents 1. Introduction 2. Do-file or program? 3. Macros 4. Branching and Looping 5.
