How to predict sales per year quarter.

var predict = require("brain-predict") ;

var config = {
    // how many steps to predict
    predictionSteps : 8,
    // how many steps use for each training pattern
    step : 4,
    // input data
    serie : [

    ]  
}

var prediction = predict.predict(config) ;

console.log("PredictionSerie\n" + prediction.prediction + "\n");
console.log("Mean error: " + prediction.meanerror) ;

Result for 2 quarters
