installation

go get github.com/sajari/regression

usage

Import the package, create a regression and add data to it. You can use as many variables as you like, in the below example there are 3 variables for each observation

import "github.com/sajari/regression"

func main() {
    var r regression.Regression
    r.SetObservedName("Distance")
    r.SetVarName(0, "Weight")
    r.SetVarName(1, "Height")
    r.SetVarName(2, "Blood sugar")
    r.AddDataPoint(regression.DataPoint{Observed : 98, Variables : []float64{483, 343, 0.0386}})
    r.AddDataPoint(regression.DataPoint{Observed : 75, Variables : []float64{227, 419, 0.0705}})
    r.AddDataPoint(regression.DataPoint{Observed : 0, Variables : []float64{380, 666, 0.0245}})
    r.AddDataPoint(regression.DataPoint{Observed : 20, Variables : []float64{85, 833, 0.0567}})
    r.AddDataPoint(regression.DataPoint{Observed : 50, Variables : []float64{188, 182, 0.0143}})
    r.RunLinearRegression()
    r.Dump(true)
}
