Fast-dm-30.2 implements an guessing parameter p (see Ratcliff & Tuerlincks, 2004). p estimates the amout of guessings in your data with the assumtion of an equal RT distribution of guesses between the fastes and the slowest response. For most applications, you want to set p to 0, especially when using small trial numbers. Additionally, fast-dm-30.2 comprises some minor corrections of code. Note: The file win32erf.c, needs to be included only if an elder version of Visual Studio is used for compilation.
