The mod el formula now includes -1 forbidding the use of a constant term (‘intercept’). The model
fitted here is
λ
(u) = exp(
γ
G
out
(u) +
δ
G
in
(u)) (9.13)
where G
in
(u) = G(u) is the indicator of the greenstone as before, and G
out
(u) = 1G(u) is the indi-
cator of the complement of the greenstone. T he estimates of
γ
and
δ
are 8 .103 an d 4.123 respec-
tively. The estimates of the intensities are
λ
out
= exp(8.103) = 0.0003026 outside the gree nstone

λ

= exp(4.123) = 0.0 162 inside . The two fitted models agree, but are para metrised
differently. The last few lines of output give standard errors and confidence intervals for the pa-
rameters
γ
and
δ
, and indicate that these parameters are ...
