One method for transforming an incomplete time series into a full time series using Pandas is to use the resample
method. This method can be used to resample the time series at a specified frequency and fill in missing data using various interpolation methods, such as forward filling or backward filling.
Here is an example code snippet:
import pandas as pd
# create an incomplete time series
dates = pd.date_range(start='2021-01-01', end='2021-01-10', freq='2D')
values = [1, 2, 3, None, None, 6, None, 8, 9, None]
df = pd.DataFrame({'value': values}, index=dates)
# resample to fill in missing data
df_resampled = df.resample('D').ffill()
print(df_resampled)
In this example, we create an incomplete time series with missing values using pd.DataFrame
. We then use the resample
method to resample the time series to a daily frequency and fill in missing data using forward filling. The resulting full time series is stored in df_resampled
.
Note that other interpolation methods can be used, such as backward filling (bfill
) or linear interpolation (interpolate
).
