Resampling
Resampler objects are returned by resample calls: pandas.DataFrame.resample()
, pandas.Series.resample()
.
Indexing, iteration
Groupby iterator. | |
Dict {group name -> group labels}. | |
Dict {group name -> group indices}. | |
| Construct DataFrame from group with provided name. |
Function application
| Aggregate using one or more operations over the specified axis. |
| Aggregate using one or more operations over the specified axis. |
| Call function producing a like-indexed Series on each group and return a Series with the transformed values. |
| Apply a function func with arguments to this Resampler object and return the function's result. |
Upsampling
| Forward fill the values. |
| Backward fill the new missing values in the resampled data. |
| Backward fill the new missing values in the resampled data. |
| Forward fill the values. |
| Resample by using the nearest value. |
| Fill missing values introduced by upsampling. |
| Return the values at the new freq, essentially a reindex. |
| Interpolate values according to different methods. |
Computations / descriptive stats
Compute count of group, excluding missing values. | |
| Return number of unique elements in the group. |
| Compute first of group values. |
| Compute last of group values. |
| Compute max of group values. |
| Compute mean of groups, excluding missing values. |
| Compute median of groups, excluding missing values. |
| Compute min of group values. |
| Compute open, high, low and close values of a group, excluding missing values. |
| Compute prod of group values. |
Compute group sizes. | |
| Compute standard error of the mean of groups, excluding missing values. |
| Compute standard deviation of groups, excluding missing values. |
| Compute sum of group values. |
| Compute variance of groups, excluding missing values. |
| Return value at the given quantile. |
