Resampling Time Series Data: A 3-Step Solution for Upscaling and Aggregation
The solution is a three-step process: Upsample by minute: Use the resample method with frequency ‘T’ (time) and fill forward (ffill) to assign to each minute that has an event, the value of that event. Resample by hour: Use the resample method again, this time with frequency ‘H’ (hour), and take the mean in each interval using the mean function. Here’s a Python code snippet that demonstrates this process: import pandas as pd # Load your data into a DataFrame s = pd.
