Miraplacid Data Analyzer Plug-ins Guide

Calculates count, minimum and maximum value, ME and Dispersion for an input data.

Parameters list:

• Count (Y/N)
• Min (Y/N)
• Max (Y/N)
• ME (Y/N)
• DISP (Y/N)

Parameters turn on/off lines of calculation results.

Calculates compressed size and bit/symbol ratio for an input data for order-0 adaptive arithmetical coding for different probability increment value.
The most of compression algorithms utilize probability increment "1".

Parameters list:

• Shrink ranges (Y/N) - analyses input alphabet range and shrinks the range if possible. For example, for CSV file it would shrink the alphabet from 0..255 to 44..57 (44 is ",", 57 is "9", so compression ratio will be higher.
• Calculate for 1 (Y/N)
• Calculate for 1/2 (Y/N)

Calculate the result for probability increment equal to "total" or "total/2".
It's too high probability increment values and they slow down the calculation dramatically (due to probabilities re-scaling), so they are turned off by default.

Counts occurrences for symbols or symbol pairs.
Calculates compressed size and bit/symbol ratio for non-adaptive order-0 arithmetical coder.

Parameters list:

• Sort (Y/N) - sort results
• For pairs (Y/N) - calculates results for symbol pairs rather than for individual symbols.
• Items to show (Integer) - show only particular amount of first results - very useful with "Pairs" and "Sort".

Correlation analysis (for CSV files only).
Requires more than one column of data.
Calculates ME and Dispersion for all the columns of data.
Calculates K xy and r xy between the first and every other column of data.

Parameters list:

• Show ME (Y/N)
• Show D (Y/N)
• Show K xy (Y/N)
• Show r xy (Y/N)

Parameters turn on/off columns of calculation results.

Regressive analysis (for CSV files only).
Requires more than one column of data.
Calculates linear regression equation coefficients.
The first column considered as "Y", the others - as a X1..Xn

Parameters list:
None

Counts average distance between the symbols occurrences.

Parameters list:

• Sort (Y/N) - sort the results
• Items to show (Integer) - show only particular amount of first results - very useful together with "Sort".
