چکیده

In 2022, the COVID-19 virus is still making headlines in various mass media because it a that very dangerous to health. The world health organization, WHO, explained caused global pandemic infected whole world. condition of has not yet turned into an endemic. Based on total confirmed positive cases, Indonesia ranks 18th out 222 countries. To determine influence factors survival analysis one techniques could be applied. One most commonly used models Accelerated Failure Time (AFT) model. AFT model, required check assumptions regarding feasibility distribution form. this study, distributions are Weibull, Exponential, Log-normal, and Log-logistics distributions. We compare each get best model analyze death cases due COVID-19. Comparisons made by comparing AIC values distribution. selected based smallest value. with log-normal as value 142.763. for compared other distributions.Keywords: accelerated failure time model; COVID-19; mortality analysis; analysis.
