Description
The list below shows the different number of combinations of occurrence categories reported in the ADREP since 2005. It shows how many accident reports have been filed with each respective occurrence category, as well as the frequency of certain combinations. The total number of reports for each combination is then tested under a chi-square distribution model, to find the significance of each relationship (Determined if chi-square value is greater than 3.84).
To filter only those occurrence categories which have significant relationships, Click on the "Significant" bar and select the filter "Yes".
For details concerning this taxonomy, please consult the Occurrence category taxonomy in the ADREP corner on SKYBRARY.
