This is a tool to statistically evaluate the performance of a filter on previous winning numbers draws.
Selected filter is first applied to all tickets generated from a given range of numbers. The statistics of number occurrences are calculated for tickets that passed the filter. The resulting table then shows how many numbers of the most frequent ones match the actual winning numbers.
The statistics calculation can be replaced with other application features:
Hits Table: The first table column shows the draw date, the second column contains the drawn winning numbers. The rest of the table columns show how many numbers of the most frequently occurring ones match the actual winning numbers. For example, if column First 6 shows value "2", then the winning numbers at this row contain two numbers of the six most frequent numbers. Value "4" in column First 20 means that the twenty most frequent numbers include 4 winning numbers. Place your mouse cursor over any table cell to see a tooltip with the list of matching numbers.
Hits Chart: Shows data from the Hits Table as a chart. Use button Options to see chart data for other columns from the Hits Table.
Numbers Table: Shows number occurrences for tickets that passed filter's conditions. The total number of tickets that passed the filter is also available.
Numbers Chart: Shows data from the Numbers Table as a chart.
Note: If you select a filter that
depends on the winning numbers database (Match
Winning Numbers, Winning
Numbers History or any compound
or group filter containing any
of these two), the statistics calculation will differ slightly. The calculation
process will take longer because it will consist of several repeated step.
The number of step depends on the option Show filter hits for.
In each step the winning numbers database must simulate the situation
when the last draw in the database is the latest date moved by the appropriate
number of draws back to the history. It is necessary to ensure the correct
evaluation of WN Selection option Latest XX in these
two filters.
The data in the Numbers Table and Numbers Chart will
differ according to the row (draw) currently highlighted in the Hits
Table.
Example [Expert Lotto 6/49]
The resulting table will be similar to this:
From the resulting statistics we can see that after applying the selected filter there is one drawn number in the first six most frequent numbers (the first column) in four of the test draws. In six out of ten test draws there are two or more drawn numbers in the first 15 most frequent numbers (numbers of the tickets left after filtering) - column First 15.
Note: Page Filter Statistics is similar to Back-test feature, which shows how many past draws meet the filter criteria. However Filter Statistics evaluates the frequency of the numbers of tickets that passed the given filter. If you manage to find a filter that yields for example four or more winning numbers in the first 15 for most of the test draws then it might be a good idea to filter a full package with such a filter and then setup a wheel from 15 most frequent numbers from the filtered package.
