👉 Differenciel is a German word that means "differently" or "different". It can be used to describe how two things are different from each other, such as in terms of their differences in size, shape, color, etc.
👉 Differencing is a statistical method used to calculate changes or differences in a series of data points over time. It involves subtracting one variable from another, either by replacing it with zero (constant difference) or by using an indicator function (linear difference). The goal is to identify changes in the values that occurred within a specific period of time. Differencing can be applied to both continuous and categorical variables.
