TI  - ESTIMATION OF DAILY CASES OF COVID-19 AND REPRODUCTION NUMBER IN USA, 
GERMANY, INDIA, RUSSIA, ITALY, SPAIN, FRANCE, UNITED KINGDOM, BRAZIL 
USING DISCRETE TIME GOMPERTZ MODEL AND ADAPTIVE KALMAN FILTER
AB  - In this study, cumulative and daily cases are estimated online using discrete-time Gompertz model (DTGM) and Adaptive 
Kalman Filter (AKF) based on the total COVID-19 cases between February 29-July 28, 2020 in USA, Germany, India, Russia, 
Italy, Spain, France, United Kingdom, Brazil. Employing the data collected between February 29 and July 28, 2020, it is 
showed that the DTGM in conjunction with AKF provides a good analysis tool for modeling the daily cases made using the in 
terms of mean square error (MSE), mean absolute percentage error (MAPE), and 
$R^2$ .
