2.1 Statistics for Numeric Fields
BigML computes the measures below based on all instances of a given numeric field and displays these measures in a histogram, as seen in Figure 2.2 :
Minimum: the minimum value found in this numeric field.
Mean: the arithmetic mean of non-missing field values.
Median: the approximate median of the non-missing values in this numeric field.
Maximum: the maximum value found in this numeric field.
Standard deviation: the unbiased sample standard deviation.
Kurtosis: the sample kurtosis. A measure of ’peakiness’ or heavy tails in the field’s distribution.
Skewness: the sample skewness. A measure of asymmetry in the field’s distribution.
