For the parameter estimation of epidemic models usually fminsearch, fmincon functions of Matlab are used. However, there is a lack of detailed informations regarding how to choose the initial values and coding for estimation. Due to this, as a beginner in this field, I'm suffering. Could anyone help me with this? I would like to get your suggestions and guidance for this issue.
You need to obtain values from published papers and if you can perform some small scale experiments. Usually the model does not estimate the parameters themselves. You need to estimate them yourself first. Then the model can apply an appropriate distribution for them using some basic values :)
To a great extent, the initial values depend on your model boundary conditions. Preferably an initial value is taken when a significant step change in model outcome is observed.
