ISYE 6402 TIME SERIES ANALYSIS MIDTERM 1 PRACTICE EXAM: MT.
EVEREST TEMPERATURE DATA | QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) PLUS RATIONALES 2026 Q&A | INSTANT
DOWNLOAD PDF
Core Domains:
• Weak Stationarity and Strict Stationarity Conditions
• Autocorrelation Function (ACF) and Partial Autocorrelation
Function (PACF) Interpretation
• White Noise Processes and Model Diagnostics
• ARIMA Model Identification, Estimation, and Forecasting
• Unit Root Testing (ADF Test) and Differencing
• Trend and Seasonality Decomposition (Splines, LOESS,
Polynomial Regression)
• Model Selection Criteria (AIC, BIC) and Residual Analysis
• Time Series Regression and Dynamic Linear Models
• Forecast Evaluation (RMSE, MAE, MAPE) and Confidence
Intervals
Introduction:
This comprehensive practice examination is designed to evaluate foundational
knowledge and applied analytical skills in time series analysis, specifically
within the context of hourly temperature data at the Mt. Everest Base Camp
during 2020. Each data point represents a temperature measurement in
degrees Fahrenheit taken at hourly intervals. The exam covers critical concepts
including stationarity, autocorrelation, ARIMA modeling, trend decomposition,
and forecasting. Candidates will demonstrate their ability to interpret
ACF/PACF plots, apply unit root tests, select appropriate models using AIC/BIC,
and evaluate forecast accuracy using metrics like MAPE. Emphasis is placed on
real-world application using both full-year and abridged (first two months)
datasets. Successful completion ensures readiness for advanced time series
analysis and data-driven decision-making in industrial and systems
engineering contexts.
