Of course if you are on the Statalist you already know. Details here. New features include a proper editor with syntax highlighting, full pdf documentation, support for interaction terms typed directly in your estimation expression -- the lack of which used to be a reason to prefer R -- and a full kit of object-oriented features in Mata.
Stata 10 may well be my last Stata license under Windows.

If you collaborate with people who use other statistical software with proprietary data file formats, you will find Stat/Transfer useful for converting between Stata and said software. How to do that using the Stat/Transfer GUI is easy enough to figure out. But you can also run Stat/Transfer from within Stata. If you are on a [...]

Occasionally a need arises to move things between computers. You might, for example, be getting about 20 gigabytes of data per week, use it to re-run your model so your parameter estimates stay up to date, and then you must make room for next week's batch.
For this sort of job you probably have a remote [...]

Local access to an NFS share is useful enough that I want it enabled by default, without the need for the mount command as shown in my previous post.
This default access to the server share also goes by the name "auto-mount". You have two options for setting it up: using the autofs utility or a [...]

I set up Samba a while back, and that turned out to be a great way to get stuff I used to keep on separate Windows computers all in one place on the FreeBSD box, as readily accessible as if they were still on the original local hard drives. Now I'd like to do the [...]

I'm messing around with Ubuntu Hardy on a Dell Latitude D400 that got a new lease on life with a refurbished keyboard, battery, hard drive, an extra 1G of RAM and new rubber feet. Hey, the rubber feet are important. The times may be tough, and this little box may be old, but I won't [...]

A couple of days ago I showed how you can use logical operators inside arithmetic expressions. The point of that post was that if you had three variables, called say _var1, _var2 and _var3, then you could build another variable, call it _var4, that counted row-wise their non-zero instances, like so:
gen _var4=(_var1!=0)+(_var2!=0)+(_var3!=0)
This was actually spun [...]

If you were looking up something Stata-related and Google sent you here, you may or may not be in the right place. What I know for sure is that you should definitely join the Statalist. I've benefited lots over the years from lurking there. Here's the latest example: somebody asked yesterday about an easy way to [...]

I came across a data set with some variables in it that recorded actual measurements, so their values could be zero or higher. Then a need arose to quickly look up how many of these variables would have recorded anything -- in effect, separating the yes/no part from the how much -- and adding the [...]

What can a Stata user do with a Samba server? Pretty much the same thing you would do with any computer. My Stata is installed on my Windows PC. Now Samba allows me to store either do-files or data on the remote FreeBSD server and access them easily.
Suppose that the remote box were called myUnix. [...]
