Stan is a small console application that works on all Unix systems. It is
|
|
able to generate several statisical information of a stream. A stream can
|
|
be either standard input or given files. Stan can be used in order to analyse
|
|
encrypted data or to measure the quality of a pseudo random number generator.
|
|
|
|
There are three types of statistics generated by Stan:
|
|
|
|
- General Statistics
|
|
General statistical standard values are based on the bytes of the input
|
|
stream. Stan is able to calculate the mean, the median, the deviation
|
|
and the chi-squared value of the given stream.
|
|
|
|
- Pattern Statistics
|
|
It is possible to do pattern analysis up to a specified pattern length.
|
|
Stan will analyse the patterns inside the stream and output the most
|
|
used patterns and the range of patterns used.
|
|
|
|
- Bit Statistics
|
|
By analysing the bit of the given stream and dividing them into run,
|
|
sequences of the same bit, stan is able to show information that are
|
|
useful for analysing pseudo random numbers. Stan calculates ratios
|
|
between run lengths and 0 runs to 1 runs.
