Programming Procedure in Excel for Calculating Model Variables in a New SEIR Epidemic Model Based on the latent-infectious period chronological order
Our new SEIR epidemic model built from the l-i AIR model  has similar terms to the conventional SEIR epidemic model . We have uploaded an instruction file for describing how to write a calculation program in Excel for calculating the model variables S, E, I, R and y. REFERENCES  Liu, X.
