More than a month without updating... Yes, I was busy doing something else, and that was traveling. I was lucky enough to enjoy a period of free time, and relaxed myself pretty well.

Now it is the time to start something useful, since the spring festival has gone. I need to be responsible for my promise. Therefore, I choose to begin to write the brochure about econometrics and R, the most up-to date statistic software.

### Name

Play Econometrics with R

I use "play" to avoid being responsible for any potential academic faults 🙂 Indeed, I will correct the bugs as soon as I know.

### Aim

In this brochure, I'll introduce typical econometric methods one by one and their realization in R. Of course, a huge volume of examples and data will appear (and that is the most knotty problem for me at the moment). I'll cover some public examples (i.e. published ones from current books, e.g *Introductory Econometrics: A Modern Approach* by Jeffrey M. Wooldridge), and also some meaningful ones (applications in different fields) from scholar articles with data published. I should admit it is a really challenging task, and I need many helps from friends.

### Readers

I hope this brochure can be helpful for those groups:

- the statistics students who begin to know and use econometrics, especially for economic problems.
- the economics students who want to improve their analysis with a more powerful tool -- R, instead of Stata or SPSS.

This brochure will help the first group see how econometrics functions in economic analysis, and will bring introductory guide for the second group.

### Remarks

More features needed to be announced here:

- This brochure is totally free, and will published regularly on the Internet. If possible, it will be realized with the help through Git of Cos.name, the biggest online statistics community in China.
- I'll use Latex (Lyx) + Sweave + R as my tools. For more information about this combination, please see here (in Chinese from Yihui's Blog) .
- At present, this brochure will be written in Chinese (I'm really sorry). But after several revisions, and if anyone calls for needs, I will rewrite another version in English.
