Open Stata 13 data files in Stata 12

I just ran across a very useful ado.-file called use13 which allows to open files in Stata 12 which were originally saved in Stata 13 (which often results in the error code “r(610): file not Stata format”). use13 can be installed by typing

ssc install use13
use13 filename.dta

This will then convert the Stata13 data file to use in Stata12.

Note: An alternative to use13 is to use saveold when creating the data file in Stata 13 (instead of save):

saveold filename [, saveold_options]

Use images from pdf documents in Latex

While you can simply drag & drop images in MS Word or Powerpoint, doing this in Latex requires a few more steps. An important difference is that in Latex, you first need to save the copied file as a separate image file which can then be included in the Latex code. For this purpose, we need a decent image editor. I recommend using Continue reading

Formatting Tables in Latex

There are a lot of sources giving advice on how to format your Latex tables. Adrian P. Robson ( wrote a very good and comprehensive guide on formatting tables in Latex. Just follow the following link to download the PDF file:

Data storage type matters

Despite most sources tell that the storage type in stata should not matter, it is worth checking whether this is the case for your dataset. I just came across a situation where two identically constructed datasets (one stored in default type (float) and one stored in double) generated different output. Also before that i encountered a problem with person identifiers in the GSOEP if using the default data storage. If your dataset is not huge (with the GSOEP it still works quite ok) it might be worth to take the safe side and use

 set type double 

before you assemble your data set. This saves the data in the most precise way stata offers.

Turning Footnotes into Endnotes …

Submitting (LaTeX) written papers has some advantages: one usually does not have to change any formatting manually. LaTeX does that for us if it is instructed to do so. Journals often want the submissions to be formatted in a peculiar way. My challenge was to change footnotes to endnotes. I did remember that it was easy in LaTeX, but not how it was done, so Google had to help me …
