In the attached mdl model (from Erik Pruyt 1806 seasonal flue) 1806 Seasonal Flu.mdl there is a biflow between two stocks of immune population and susceptible population driven by a seasonal fraction (with 1st order delay). For the seasonal bi-flow the description reads Background But not everyone i...

Thanks Tom
I went with 0.5+0.34*SIN((Time-4.7)/12*(2*3.14159))
I imagine it could simplify or be rearranged

I am trying to model a seasonal fluctuation for an immunity fraction The model setting in months and runs for 60 months 3rd week of January 0.16 and 3rd week of July 0.84 repeating is required I understand I should have Time as input (shadow variable) into Seasonality and 0.5-0.34xSIN(?), i.e. (Time...

Thanks .. I have been correcting. v. helpful

Thanks Tom
I get the idea but seem to have still screwed something up there
Cheers for any further advice on mdl below

Hi there.
