+# Apple Stock
+
+This dataset concerns the daily close price and volume of Apple stock around
+the year 2000. The dataset is sampled every 3 observations to reduce the
+length of the time series.
+
+Data retrieved from [Yahoo
+Finance](https://finance.yahoo.com/quote/AAPL/history?period1=850348800&period2=1084579200&interval=1d&filter=history&frequency=1d).
+We use the Python package ``yfinance`` to download the data as it can not be
+redistributed as part of this repository.
+
+Since the original data has observations only on trading days, there are
+arguably gaps in this time series on non-trading days. However we consider
+these to be consecutive, and thus also consider the sampled time series to
+have consecutive observations.
