Hi all: I would like to pick your brain on the usage of "," and ";" in statistical notation in other European countries. In Turkey ve use comma as the decimal seperator and I intend to follow this in my econometrics lecture notes. I prepare my notes using LaTeX and I want them to be perfect not only in content but also in grammar and punctuation. Using for example N(9,6, 1,34) looks confusing. Also, within text using for example "the four variances respectively are 0,2, 0,4, 0,6 and 0,8..." is problematic. I can solve the problem using N(9,6; 1,34) for the first example and using "the four variances respectively are 0,2 and 0,4 and 0,6 and 0,8..." for the second example. Now, the other option is to employ the US standard notation of using dots as the decimal seperator but being the perfectionist that I am, I would be uncomfortable seeing commas in the various gretl screenshots (from Turkish translation) used in my lecture notes while I am using dots in the text myself. So my question is: How common is the use of comma as the decimal seperator in econometric texts in other European countries? I am guessing that some authors say in Germany, Italy or France would use "," while some prefer using "," but can you say one is more accepted than the other? Are students used to seeing and dealing with both types of notation that they see in different sources? I am currently leaning on using commas but I guess I will use dots if that is the general approach in econometric textbooks even in Europe. I appreciate any feedback and comments Talha -- “Remember not only to say the right thing in the right place, but far more difficult still, to leave unsaid the wrong thing at the tempting moment.” - Benjamin Franklin (1706-1790) --
