WebApr 27, 2011 · A common technique for handling negative values is to add a constant value to the data prior to applying the log transform. 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. WebJan 8, 2024 · 11. The standard explanation would go like this: Any complex number z can be written in polar form: z = z e i θ.
