Maternal Mortality Ratio time series (per 100,000 live births) 2011–2019, and recorded* versus predicted** values for 2020, with 95% confidence interval. Bahia, Brazil, 2011–2020. Source: Brazilian’s Mortality Information System (SIM/DATASUS) and Live Birth Information System (SINASC/DATASUS). *Data updated on February 04, 2021. ** Values for 2020 predicted by Holt-Winters additive exponential smoothing, based on the 2011–2019 yearly MMR time series. Smoothing coeficients: Alpha = 0.75; Beta = 0.00; Gamma = 0.00. Forecast Accuracy: Scaled Mean Absolute Error (MASE) = 0.75; Symmetric Mean Percentage Absolute Error (sMAPE) = 0.07; Mean Absolute Error (MAE) = 4.56; Root of the Mean Quadratic Simulation Error (RMSE) = 5.53
