The Statistics node provides basic summary information about
numeric fields. It calculates summary statistics for individual fields and correlations between
fields.
Example
stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")
node = stream.create("statistics", "My node")
stream.link(typenode, node)
# "Settings" tab
node.setPropertyValue("examine", ["Age", "BP", "Drug"])
node.setPropertyValue("statistics", ["mean", "sum", "sdev"])
node.setPropertyValue("correlate", ["BP", "Drug"])
# "Correlation Labels..." section
node.setPropertyValue("label_correlations", True)
node.setPropertyValue("weak_below_absolute", 0.25)
node.setPropertyValue("weak_label", "lower quartile")
node.setPropertyValue("strong_above_absolute", 0.75)
node.setPropertyValue("medium_label", "middle quartiles")
node.setPropertyValue("strong_label", "upper quartile")

weak_label
|
string | |
medium_label
|

weak_below_probability
|
number | When correlation_mode is set to Probability, specifies the
cutoff value for weak correlations. This must be a value between 0 and 1—for example, 0.90. |
strong_above_probability
|
number | Cutoff value for strong correlations. |
weak_below_absolute
|
number | When correlation_mode is set to Absolute, specifies the
cutoff value for weak correlations. This must be a value between 0 and 1—for example, 0.90. |
strong_above_absolute
|
number | Cutoff value for strong correlations. |
