python-scipyHow do I use Python Scipy to calculate quantiles?

Scipy is a powerful Python library for scientific computing. It includes a module for calculating quantiles, scipy.stats.mstats.mquantiles. The mquantiles function takes in an array of values and a set of quantiles and returns an array of the same size as the quantiles given with the values in the input array that correspond to the given quantiles.

Example code

import scipy.stats

# Create an array of values
values = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# Calculate the quantiles for the array
quantiles = scipy.stats.mstats.mquantiles(values, [0.25, 0.5, 0.75])

# Print the results
print(quantiles)

Output example

[3. 5. 7.]

Code explanation

• import scipy.stats: imports the scipy module for scientific computing
• values = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]: creates an array of 10 values
• scipy.stats.mstats.mquantiles(values, [0.25, 0.5, 0.75]): calculates the quantiles for the given array and quantile values
• print(quantiles): prints the results
