The transformation is therefore log ( Y+a) where a is the constant. Some people like to choose a so that min ( Y+a) is a very small positive number (like 0.001). Others choose a so that min ( Y+a ) = 1. highland cow on toiletWebWhen a number is raised to log whose base is same as the number, then the result is just the argument of the logarithm. i.e., a log a x = x; Here are some examples of this property. 2 log 2 5 = 5; 10 log 6 = 6; e ln 3 = 3; Negative Log Property.
