SciPy - Curve Fitting and Regression

Which scenario best describes when to use scipy.optimize.least_squares in data analysis?

ATo minimize the sum of squared residuals between observed and predicted values

BTo calculate the mean of a dataset

CTo perform classification of categorical data

DTo generate random samples from a distribution

Step-by-Step Solution

Solution:

Step 1: Understand the purpose of least squares
Least squares methods minimize the sum of squared differences between observed and model-predicted values.
Step 2: Identify the correct scenario
To minimize the sum of squared residuals between observed and predicted values correctly describes this goal, while others relate to different tasks.
Final Answer:
To minimize the sum of squared residuals between observed and predicted values -> Option A
Quick Check:
Least squares is for fitting models by minimizing residuals [OK]

Quick Trick: Least squares minimizes residual errors [OK]
