The expected number is calculated under the assumption that individual occurrences occur randomly with an identical rate over time.
Or would the stunning blow come only when I returned to the spot where the occurrence occurred?
A sharp decrease in fire occurrence occurred in the study area at the beginning of the Neoglacial period (3500 0 cal. BP), especially at lakes Aurélie and Twin, likely in response to a cooler and wetter climate (Garralla and Gajewski 1992; Viau and Gajewski 2009).
Positive associations were also observed in the present study between IFNγ and Stat-Pak (where a positive co-occurrence occurred 3.3 times as often would be as expected by chance: β = 2.5, approximate z statistic = 10.8, p<0.001), and between IFNγ and culture (3.9 times that expected by chance: β = 2.6, approximate z statistic = 2.1, p = 0.04).
I recently had this exact occurrence occur.
When such an occurrence occurs over the tropics in concert with the Intertropical Convergence Zone, it is known as a monsoon trough.
Table 4 Confusion matrix Landslide occurrence Occurred (yes) Occurred (no) Landslide prediction Predicted (yes) True positive (TP) False positive (FP) Predicted (no) False negative (FN) True negative (FN).
The most number of earthquake occurrences have occurred in intervals ( 4 < MB ≤ 4.5 ) Open image in new window.
Overall, the total number of fever occurrences that occurred among 91 415 person-days was 229.
Adverse clinical occurrences that occurred in the ICU outside of the hours of direct observation were identified in several ways.
