Confusion on units for the Poisson distribution when it is used to model variables with units
Let us handwave away the discrete/continuous issue and pretend that the times have been discretized by a hypothetical researcher, and they're in units of minutes.
So let us say that when expressed in ...

What variable type to choose for a Poisson distributed variable if software package only allows for nominal, ordinal or continuous
Poisson-distributed data are numeric count data. So a strictly nominal coding, which would treat each count value as a separate unordered level of a multi-level categorical variable, would seem to be ...

Goodness of Fit for (presumably) poisson distributed data
So I think the Chi-square approach works OK for low mean Poisson data, since setting the bins at integer values is the logical choice. With higher means though, it becomes more tricky -- you will get ...
