In addition to calculating two types of statistics, Hex Editor Neo also calculates some cumulative values for statistics results.
Descriptive Statistics
Descriptive Statistics is calculated for both General Statistics and Pattern Statistics results and is a standard statistical calculation for a random value distribution. The following values are calculated:
Mean
Sample Variance
Standard Deviation
Standard Error
Kurtosis
Skewness
Median
Mode (one or several)
Range
Minimum value
Maximum value
Sum
Entropy Analysis
Entropy analysis is performed for General Statistics mode only. The single-byte (256 different symbols) alphabet is used in entropy calculations. The following values are computed:
Entropy
Entropy value in bits and as percentage from maximum (which is 8 for selected alphabet). The higher entropy, the less redundancy in the file.
Redundancy
Redundancy equals to 100% - Entropy as percentage. Indicates the data redundancy in a file (or selection).
Compression size limit
Theoretical compressed size limit. Again, as a simple single-byte alphabet is used in computing entropy, this “theoretical” limit may be much larger than the real compressed file size, produced by any modern compressor, as they use advanced alphabet selection strategies.
