Poisson-Gamma computation (parameters and likelihood)
...rds the likelihood distribution.
#Having the *react* table, I name the columns (with y=deaths, and
x=exposures)

*yr <- react[,2]*
*xr <- react[,1]*
#I then compute the likelihood
*poislike=dpois(yr, theta*xr)*
#And this is what I come up with, which I really don't understand.
*poislike*

The values shouldn't be all null, otherwise my posterior cannot be computed
properly. Does anyone have any idea on where I could possibly have messed it
up?
Thank...
