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
