Statistics

This is where you choose what type of statistics you want to calculate on your 1D, 2D or 3D data file. Due to memory constrains, you will only be able to choose one type of statistics for your output file, when you are generating sta­tistics for matrix or volume series.

The following statistical parameters can be calculated:

·         Maximum value
Maximum value of all data

·         Minimum value
Minimum value of all data

·         Mean value
Mean value of all data, calculated by Eq. (19.5)

·         Standard deviation
Standard deviation of all data, calculated by Eq. (19.7)

·         Median value
Value below which 50% of the data fall

·         Exceedance percentage
Percentage of exceedance given a threshold value

Note: Missing values may be excluded from the calculation. I.e. if a value is missing 50 pct of the time and otherwise constantly has a value of 5, then with a threshold of 4 the exceedance percentage will be 100% if missing values are excluded. Otherwise the exceedance percentage will be 50%.
