The Means node compares the means between independent groups or between pairs of
related fields to test whether a significant difference exists. For example, you could compare mean
revenues before and after running a promotion or compare revenues from customers who didn't receive
the promotion with those who did.
Example
stream = modeler.script.stream()
sourcenode = stream.findByID("id46WRP1285C")
node = stream.create("means", "My node")
node.setPropertyValue("means_mode", "BetweenGroups")
node.setPropertyValue("grouping_field", "BP")
node.setPropertyValue("test_fields", ["Age", "K", "Na"])
stream.link(sourcenode, node)
meansnode properties |
Data type | Property description |
|---|---|---|
means_mode
|
BetweenGroups
BetweenFields
|
Specifies the type of means statistic to be executed on the data. |
test_fields
|
[field1 ... fieldn]
|
Specifies the test field when means_mode is set to
BetweenGroups. |
grouping_field
|
field | Specifies the grouping field. |
paired_fields
|
[[field1 field2]
[field3 field4]
...]
|
Specifies the field pairs to use when means_mode is set to
BetweenFields. |
label_correlations
|
flag | Specifies whether correlation labels are shown in output. This setting applies only when
means_mode is set to BetweenFields. |
correlation_mode
|
Probability
Absolute
|
Specifies whether to label correlations by probability or absolute value. |
weak_label
|
string | |
medium_label
|
string | |
strong_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
