Max deviation refers to the maximum difference between a value in a dataset and the mean or median of that dataset. In statistics, deviation helps to understand the dispersion and variation of data points within a dataset. It is an important concept often used in financial analysis, signal proc...

It gets the max value for both columns X and Y and finally returns a Series object with the max of each column.To find the max of a particular column of DataFrame in Pandas, we call the max() function for that column only.import pandas as pd df = pd.DataFrame({'X': [1, 2, 2...

Example 1: Maximum & Minimum by Group in pandas DataFrameIn this example, I’ll show how to calculate maxima and minima by one grouping column in Python.We can compute the max values by group as shown below…print(data.groupby('group1').max()) # Get max by group # x1 x2 group2 ...
