Dear John (again), I was surprised that you were unable to find an existing R function that estimates a probit model by IV and so I tried a Google search for "probit instrumental variables R", which turned up the ivprobit package as the first hit. That package is also mentioned in the Economet

Hi Admire, Your attachment didn't get through, although CSV format should. The code you included seems a very roundabout way to extract a series of dates as character strings and as there is no assignment of return values in some lines, is unlikely to work. Perhaps if you send just a few of the ori

The length of time it takes to learn R is dependent on what you want to use R for. Let's assume you want to use R to perform basic statistical analyses on your own. IMHO, the best book for self-study for this is Andy Field's book, Discovering Statistics using R, It's the best book because it gi
