Arguments

PREDICTORS

multilayer - Predictors. .

REGRESSION

rasterDestination - Regression. Path for new raster layer.

REG_RESCORR

rasterDestination - Regression with Residual Correction. Path for new raster layer.

DEPENDENT

raster - Dependent Variable. Path to a raster layer.

QUALITY

rasterDestination - Coefficient of Determination. Path for new raster layer.

RESIDUALS

rasterDestination - Residuals. Path for new raster layer.

MODEL

rasterDestination - Regression Parameters. Path for new raster layer.

LOGISTIC

boolean - Logistic Regression. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

MODEL_OUT

boolean - Output of Model Parameters. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

SEARCH_RANGE

enum of ("(0) local", "(1) global") - Search Range. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

SEARCH_RADIUS

number - Search Distance (Cells). A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

DW_WEIGHTING

enum of ("(0) no distance weighting", "(1) inverse distance to a power", "(2) exponential", "(3) gaussian") - Weighting Function. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

DW_IDW_POWER
