Context : A manufacturing company wants to predict when equipment is likely to fail, so they can schedule maintenance and reduce downtime. Dataset : The company collects data on equipment sensor readings, maintenance records, and failure events. Libraries : pandas for data manipulation numpy for numerical computations scikit-learn for machine learning matplotlib and seaborn for visualization Code : # Import libraries import pandas as pd import numpy as np from sklearn.model_selection import train_test_split from sklearn.ensemble import RandomForestClassifier from sklearn.metrics import accuracy_score, classification_report import matplotlib.pyplot as plt import seaborn as sns # Load dataset df = pd.read_csv('equipment_data.csv') # Preprocess data df['failure'] = df['failure'].map({'yes': 1, 'no': 0}) X = df.drop(['failure'], axis=1) y = df['failure'] # Split data into training and testing sets X_train, X_test, y_train, y_test = tr...

  For predicting one particular day's weather from a previous year's long weather data, a SARIMA model is generally better than an ARIMA model. This is because SARIMA models can account for seasonality in the data, while ARIMA models cannot. Seasonality is a regular pattern in the data that repeats over a fixed period of time. For example, temperature data exhibits seasonality, with higher temperatures in the summer and lower temperatures in the winter. SARIMA models can account for seasonality by including additional parameters that model the seasonal component of the data. This allows SARIMA models to make more accurate predictions for seasonal data, such as weather data. ARIMA models, on the other hand, cannot account for seasonality. This means that they may not be as accurate for predicting seasonal data as SARIMA models. However, it is important to note that both SARIMA and ARIMA models are statistical models, and they are both subject to error. The accuracy of any for...
