Additionally, excess losses are considered as that which a re-insurer is held accountable for if the exposure is in effect during the point
of period under the consideration.
Thus, for
the period under consideration, 54 per cent of Birmingham's murders were committed with handguns — slightly higher than the national average.
Types and frequency of storms, wind direction (not just speed), actual temperature range (not average and not anomaly), clouds (amount and TYPE) changes in pressure systems coming from different directions, oceanic conditions during the time
period under consideration, etc, etc, etc..
The time
period under consideration is primarily 1975 to 2005, with many studies extending to earlier decades.
It is well known that temperatures, especially the night minimum, are a little higher near the centre of a large town than they are in the surrounding country districts; if, therefore, a large number of buildings have accumulated in the vicinity of a station during
the period under consideration, the departures at that station would be influenced thereby and a rising trend would be expected.
