Significance of the ARIMA epidemiological modeling to predict the rate of HIV and AIDS in the Kumba Health District of Cameroon
Bibliographic record
Abstract
Background: AIDS is a severe medical condition caused by the human immunodeficiency virus (HIV) that primarily attacks the immune system, specifically CD4+ T lymphocytes (a type of white blood cell crucial for immune response), monocyte macrophages, and dendritic cells. This disease has significant health and socio-economic implications and is one of the primary causes of illness and death globally (UNAIDS, 2022). It presents significant challenges for public health and population well-being, both in developed and developing countries. By conducting a time series analysis, this research seeks to identify any significant changes in HIV rates over the next 4 years in the Kumba District Hospital and provide valuable insights to inform evidence-based decision-making and strategies for preventing and controlling HIV within the Kumba Health District. Materials and methods: A hospital-based retrospective study on HIV/AIDS recorded cases was conducted at the Kumba District Hospital. Using data extraction form, hospital records from 2012 to 2022 were reviewed and data extracted and used to make predictions on the number of future incidence cases. Time series analysis using Auto-Regressive Integrated Moving Average (ARIMA) model was done using Statistical Package for the Social Sciences (SPSS) Version 26. Results: According to the ARIMA parameter (p,d,q), the results for the Partial Autocorrelation Factor (p) was 1, differencing (d) was 0 and Autocorrelation Factor (q) was 0. Putting these values together, we had the ARIMA model (1,0,0) which predicted an overall increase in HIV incidence cases at the Kumba District Hospital for the upcoming Years (2023-2026). Interpretation: -value of 0.410, indicating that the model's predictions aligned well with the observed data. The model predicted an increase in the number of HIV incidence cases over the coming years (2023-2026), potentially suggesting a worsening situation. However, it is important to interpret these predictions with caution and consider other factors that may influence the incidence of HIV in reality.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
