analysis_data_summary
analysis_data_summary(data, plotting_parameter=0.0)Run the plotting-position and threshold cascade over an observation frame.
The plotting positions are the Hirsch-Stedinger censored positions, so interval and threshold observations shift the positions of the systematic record even though they carry no plotting ordinate themselves.
Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| data | AnalysisData or array_like | The observation frame, or a plain sequence of observations. | required |
| plotting_parameter | float | The plotting-position parameter in [0, 1): 0 is Weibull, 0.40 Cunnane, 0.44 Gringorten, 0.50 Hazen. |
0.0 |
Returns
| Name | Type | Description |
|---|---|---|
| dict | index, value, plotting_position, and is_low_outlier are parallel lists over the exact series; number_of_low_outliers, low_outlier_threshold, plotting_parameter, lambda (events per index), total_record_length, zero_value_relative_frequency, and the four series counts are scalars. |
Examples
>>> s = analysis_data_summary([12500, 15300, 8900, 22100])
>>> s["plotting_position"]
