Logistic regression in Python using Excel data

In the following code, we generate random sample data with two features (Feature1 and Feature2) and a binary target variable (Target) based on a simple condition. We perform logistic regression, evaluate the model using accuracy, the confusion matrix, and a classification report, visualize the results for binary classification, and interpret the coefficients.

The following is a step-by-step code example:

  1. Again, we start with importing the necessary libraries:
    # Import necessary libraries
    import pandas as pd
    import numpy as np
    import matplotlib.pyplot as plt
    from sklearn.model_selection import train_test_split
    from sklearn.linear_model import LogisticRegression
    from sklearn.metrics import accuracy_score, confusion_matrix, classification_report

    For this example, we will use a different sample dataset:

    # Step 0: Generate sample data
    np.random.seed(0)
    n_samples = 100
    X = np.random.rand(n_samples, 2)  # Two features
    y = (X...
