Bar graphs depicting the error percentage and error bar for 5-day prediction by using 9 different ML models. The green color bar indicates the model with the least percentage error, i.e., highest percentage accuracy. a For India, the ARMA model gave the highest accuracy with an error bar of 0.42. b For Bangladesh, the LRP model gave the highest accuracy with an error bar of 3.18 as compared to other models. c The ARMA model showed the least percentage error in comparison to other models for Ethiopia. d The LRP model gave the least percentage error for the Democratic Republic of Congo. e In the case of Nigeria, the ARMA model gave the least percentage error, although the error bar had a value of 7.76. f For Germany, the ARIMA model gave the least percentage error, while models like BRR and LR gave percentage error of more than 50%
