    ByVal trendType As esriGeoAnalysisTrendEnum, _
    ByVal order As Integer, _
    ByVal out_rms_file As String _
) As IGeoDataset

[C#]
public IGeoDataset TrendWithRms (

Remarks

geoData	an input point featureclass containing the points with z values to be interpolated onto a surface Raster
trendType	an esriGeoAnalysisTrendEnum specifying the type of regression to be performed esriGeoAnalysisLinearTrend polynomial regression is performed to fit a least-squares surface to the set of input points It is applicable for continuous types of data. esriGeoAnalysisLogisticTrend logistic trend surface analysis is performed It generates a continuous probability surface for binary, or dichotomous, types of data.
order	order of the polynomial It must be an integer value 1 through 12. A value of 1 will fit a flat plane to the points, and a higher value will fit a more complex surface. A commonly used value is 1.
out_rms_file	Filename for an output text file that contains information about the RMS error of the interpolation.
