This study analyzed COVID-19 daily deaths and cases in ten countries using linear regression and ARIMA models. Results show varying correlations between cases and deaths, with some nations indicating controlled spread and others an upward trend.
Area of Science:
- Epidemiology
- Biostatistics
Background:
- The Coronavirus disease (COVID-19) pandemic presents a significant global health crisis.
- Understanding the dynamics of daily deaths and new cases is crucial for pandemic management.
Purpose of the Study:
- To analyze the relationship between daily new cases and daily deaths caused by COVID-19 across ten countries.
- To predict potential daily COVID-19 deaths for the next three months using time-series forecasting.
Main Methods:
- Linear regression models were fitted to establish correlations between daily cases and deaths.
- Autoregressive Integrated Moving Average (ARIMA) models were employed for short-term death predictions.
Main Results:
- Correlation coefficients (R-squared) varied, with Pakistan (0.662) and Turkey (0.702) showing substantial explanation of deaths by cases. Iran showed a lower correlation (0.24).
- India reported the highest number of deaths, while the UAE reported the lowest.
- China, UAE, and Australia demonstrated signs of controlled pandemic spread. Pakistan, Iran, Germany, and Italy indicated an upward trend in disease spread, potentially correlating with increased mortality.
Conclusions:
- The relationship between COVID-19 cases and deaths varies significantly by country.
- Predictive models suggest differing pandemic trajectories, with some countries requiring intensified control measures.

Residuals and Least-Squares Property
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
