DeprecatedKNIME Base Nodes version 4.3.2.v202103021015 by KNIME AG, Zurich, Switzerland

This node calculates statistical moments such as minimum, maximum, mean, standard deviation, variance, median, overall sum, number of missing values and row count across all numeric columns, and counts all nominal values together with their occurrences. The dialog offers two options for choosing the median and/or nominal values calculations:

Options

Compute median values
Select this option if for all numeric columns the medians are computed. Note, this computation might be expensive, since it requires to sort all column independently to find the values that divides the distribution into two halves of the same number of values.
Column filter
Filter columns for counting all possible values.
Nominal values
Adjusts the number of counts for both, top number of frequent and infrequent occurrences of categorical values per column (displayed in the node view!).
Nominal values in output
Adjusts the maximum number of possible values per column in the nominal output table.
