Returns a series with values shifted by the specified offset. When the offset is positive, the values are shifted forward and first `offset` keys are dropped. When the offset is negative, the values are shifted backwards and the last `offset` keys are dropped. Expressed in pseudo-code: result[k] = series[k - offset] ## Parameters - `offset` - Can be both positive and negative number. - `series` - The input series to be shifted. ## Remarks If you want to calculate the difference, e.g. `s - (Series.shift 1 s)`, you can use `Series.diff` which will be a little bit faster.
