Description Usage Arguments Value Author(s) References See Also Examples

A function called by est.wt.matrix, which calculates the basic weights in the Wallinga-Teunis matrix given the time of each case occurrence and the generation time distribution of the pathogen. Code adapted from the R0 package.

1	est.wt.matrix.weights(case.times, gen.t.dist)

`case.times`	a vector giving the occurrence time for each case
`gen.t.dist`	a vector giving the generation time distribution for the infecting pathogen

a numerical matrix with the number of columns and rows equal to the number of time steps in the epidemic
