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:
- 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...
