Inverted Number Matrix provides a list
of all number pairs sorted by their occurrences. The table in the figure
below shows statistics calculated for 500 random tickets for the whole
range of drawn numbers (49).
Switching between Occurrences and Latest Draws tabs allows
displaying either occurrences or number of draws elapsed since the last
occurrence of any pair. In the first case the first column labeled"0"
shows pairs which does not exists in your selection (package tickets and/or
winning numbers draws). The other columns show how many times the appropriate
pairs occurred in the selected history and/or package. In the second case
the column header shows the number of draws elapsed since the last occurrence
of the pair in this column. Label "n/a" means that
pairs were not drawn in the selected range of winning numbers draws. Column
"0" shows pairs from the latest draw (15 pairs of 6 numbers),
column "3" then shows pairs drawn three draws ago (since the
latest draw in the selected range of winning numbers) etc.
Table columns
represent occurrences of appropriate number pairs; the occurrence values
are shown in column headers. Each table row contains number pairs with
occurrences shown in column headers. In the example above pairs 9-16 and
12-30 were not found at all; the lowest occurrence (1x) belongs to twelve
pairs in total (1-45, 3-26, 8-24, 8-45, 14-45, 19-26, 20-35, 26-27, 33-34,
34-42, 35-40, 37-42). The pairs are sorted by the first and by the second
number in the pair.
Latest Draws tab allows displaying number pairs divided into columns
according to how many draws elapsed since the last occurrence of any given
number pair in the selected winning numbers range. Column labeled "0"
then shows all number pairs from the very last draw.
You
can use Highlight number option to lookup a particular number
more easily. You can enter the number you are searching for from keyboard
or you can use scroll button . Headers of columns that contain the searched number are painted
in dark color.
Table cells containing the searched number are painted with blue background. Numbers in the pairs are sorted by their values.
500 tickets in total were used to calculate the statistics above so normal distribution should be expected. Therefore the highest amount of number pairs will occur with approximately half of the maximum occurrence.
The highest occurrences are displayed in the rightmost table column. Use the scrollbars when the table is too large.
This function is often used with filters. It is very useful to identify how filters modify the package content and to lookup, which tickets the filter 'prefers'. This function can also calculate occurrences of number pairs in any data range in the lottery history.
We can use the same logic for number pairs as when classifying numbers into hot, warm and cold numbers.
Each ticket containing 6 numbers presents 15 number pairs. The total count of all pairs from 49 numbers is 1176. It means that in case of uniform occurrences of number pairs each pair should be drawn at least once within approximately 80 draws. Calculate statistics for 80 latest draws and display the Inverted Matrix. You will find pairs that were not drawn at all and pairs that were drawn more frequently.
