title: R - Forecast multiple time-series (15K Products)
body: <p>Hi Stack Overflow community.</p>
  <p>I have 5 years of weekly price data for more than 15K Products (5*15K**52  records). Each product is a univariate time series. The objective is to forecast the price of each product.</p>
  <p>I am familiar with the univariate time series analysis in which we can visualize each ts series, plot its ACF, PACF, and forecast the series. But, Univariate time series analysis is not possible in this case when I have 15K different time-series, <strong>can not visualize each time series, its ACF, PACF, and forecast</strong> separately of each product, and make a tweak/decision on it.</p>
  <p>I am looking for some recommendations and directions to solve this multi-series forecasting problem using R (preferable). Any help and support will be appreciated.</p>
  <p>Thanks in advance.</p>
