Can someone be able to provide me with information on various approaches and procedures for creating lag and leads of a column? I am aware that there are multiple ways to accomplish this task, and although I have tried a method utilizing a Python dictionary, I believe there may be more effective alternatives. The method I used is provided below:
- I use
shift()function, it allows to move the values in a column up or down by a specified number of rows.
- A positive number of rows creates a lagged version of the column, while a negative number of rows creates a lead version of the column.
shift()function can be used to create time series features, among other things.
