onconova.core.aggregates

Module providing custom Django aggregate classes.

Median

Bases: Aggregate

Aggregate class to compute the 50th percentile (median) of a set of values.

Notes

It uses the SQL PERCENTILE_CONT function. The median is calculated as the 50th percentile (second quartile) within the ordered group of the provided expressions. The result is returned as a floating-point value.

function class-attribute instance-attribute

name class-attribute instance-attribute

template class-attribute instance-attribute

get_output_field()

Returns a Django FloatField instance to be used as the output field for this method.

Returns:

Type	Description
FloatField	A Django model field representing a floating point number.

Source code in onconova/core/aggregates.py

def get_output_field(self):
    """
    Returns a Django `FloatField` instance to be used as the output field for this method.

    Returns:
        (FloatField): A Django model field representing a floating point number.
    """
    return FloatField()

Percentile25

Bases: Aggregate

Aggregate that calculates the 25th percentile (first quartile) of a given expression.

Notes

This class uses the SQL function PERCENTILE_CONT(0.25) WITHIN GROUP (ORDER BY ...) to calculate the continuous 25th percentile (first quartile), which is commonly used to measure the value below which 25% of the data falls.

get_output_field()

Returns a Django FloatField instance to be used as the output field for this method.

Returns:

Type	Description

    Returns:

    """
    return FloatField()

Percentile75

Bases: Aggregate

Aggregate class to compute the 75th percentile (p75) of a set of values.

Notes

This class uses the SQL function PERCENTILE_CONT(0.75) WITHIN GROUP (ORDER BY ...) to calculate the continuous 75th percentile (third quartile), which is commonly used to measure the value below which 75% of the data falls.
