Question

When I upsample my time series and I find many missing values , how do I fill the missing values?
1- All the Options
2- Interpolation
3- Forward Filling
4- Backward Filling

Answer 1

Answer:

Interpolation is method so far is used for finding the missing values between two points in a coordinate system and so far is used calculating values in the graph functions.

When working with time series data, the technique of forward filling and reverse filling is used to find the missing values and often refered as the last value known.

So Option 1 All the Options is the correct one.
