(Required)

The layer containing the dependent and independent variables.

Syntax: As described in Feature input, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A URL to a big data catalog service layer with an optional filter to select specific features
• A feature collection

//REST web example
{"url": "https://myportal.domain.com/server/rest/services/Hosted/hurricaneTrack/FeatureServer/0", "filter": "Month = 'September'"}

//REST scripting example
"inputLayer": {"url": "https://myportal.domain.com/server/rest/services/Hosted/hurricaneTrack/FeatureServer/0", "filter":"Month = 'September'"}

(Optional)

A layer containing features representing locations where estimates should be computed. Each feature in this dataset should contain values for all the explanatory variables specified. The dependent variable for these features will be estimated using the model calibrated for the input layer data.

Syntax: As described in Feature input, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A URL to a big data catalog service layer with an optional filter to select specific features
• A feature collection

//REST web example
{"url": "https://myportal.domain.com/server/rest/services/Hosted/hurricaneTrack/FeatureServer/0", "filter": "Month = 'September'"}

//REST scripting example
"pointLayer": {"url": "https://myportal.domain.com/server/rest/services/Hosted/hurricaneTrack/FeatureServer/0", "filter": "Month = 'September'"}

(Required)

The numeric field containing the observed values to be modeled.

//REST web example
Earnings

//REST scripting examples
"dependentVariables": "Arrest"

(Required)

One or more fields representing independent explanatory variables in the regression model.

//REST web example
Rate

//REST scripting example
"explanatoryVariables": "Rating,Nights"

(Required)

Specifies the type of data to be modeled. This parameter can be defined as one of the following:

• Continuous—The dependentVariable is continuous. The model used is Gaussian, and the tool performs ordinary least squares regression.
• Binary—The dependentVariable represents presence or absence. Values must be 0 (absence) or 1 (presence), or mapped to 0 and 1 values using the parameter.
• Count—The dependentVariable is discrete and represents events such as crime counts, disease incidents, or traffic accidents. The model used is Poisson regression.

//REST web example
Continuous

//REST scripting example
"regressionFamily": "Binary"

(Optional)

Specifies whether a table with coefficient values will be returned. By default, the coefficient table is not returned.

Values: true | false

//REST web example
false

//REST scripting example
"generateCoefficientTable": false

(Optional)

A list of the explanatoryVariables specified from the inputLayer and their corresponding fields from the featuresToPredict. By default, if an explanatoryVariable is not mapped, it will match to a field with the same name in the featuresToPredict. This parameter is only used if there is a featuresToPredict input. You do not need to use it if the names and types of the fields match between your two input datasets.

predictionLayerField is the name of a field specified in the explanatoryVariables parameter and trainingLayerField is the field that will match to the field in the explanatoryVariables parameter.

//REST web example
[{"predictionLayerField": "CrimeType", "trainingLayerField": "TypeOfCrime"},{"predictionLayerField": "population", "trainingLayerField": "population"}]

//REST scripting example
"explanatoryVariableMatching": [{"predictionLayerField": "isSunny", "trainingLayerField": "isSunny2010"}]

(Optional)

A list representing the values used to map to 0 (absence) and 1 (presence) for binary regression. value0 is the string that will be used to represent 0 and value1 is the string that will be used to represent 1.

//REST web example
[{"value0": "NoArrest"},{"value1": "Arrest"}]

//REST scripting example
"dependentMapping": [{"value0": "Fail"},{"value1": "Pass"}]

(Required)

The task will create a feature service of the results. You define the name of the service.

//REST web example
myOutput

//REST scripting example
"outputName": "myOutput"

(Optional)

The context parameter contains additional settings that affect task execution. For this task, there are four settings:

• Extent (extent)—A bounding box that defines the analysis area. Only those features that intersect the bounding box will be analyzed.
• Processing spatial reference (processSR)—The features will be projected into this coordinate system for analysis.
• Output spatial reference (outSR)—The features will be projected into this coordinate system after the analysis to be saved. The output spatial reference for the spatiotemporal big data store is always WGS84.
• Data store (dataStore)—Results will be saved to the specified data store. The default is the spatiotemporal big data store.

{
"extent" : {extent},
"processSR" : {spatial reference},
"outSR" : {spatial reference},
"dataStore":{data store}
}

The response format. The default response format is html.

Values: html | json
