Hi, thanks for the gread library!

The following call produces a console.log which is not ideal in my case since i love a clean console ;).

Call: 

static forecastTimeseriesNpmArima({ts, exog, newExog, forecastHorizon}: ForecastArguments): Array<Array<number>> {

        // Init and fit sarimax
        const sarimax = new ARIMA({
            auto: true,
            transpose: false,
            verbose: false
        }).fit(ts, exog)

        return sarimax.predict(forecastHorizon, newExog)
    }

Log:

0.05
