(a) Run linear regression on the closing price data for BTC in the range of 12/15/2020 to 12/28/2020. Report the r-squared value on your training data. Use this to predict BTC closing prices on 1/1/2021 and 1/8/2021. How close are your predictions to the actual? Repeat with polynomial regression. (b) Run linear regression on the closing price data for BTC in the range of 2/2/2021 to 2/15/2021. Report the r-squared value on your training data. Use this to predict BTC closing prices on 2/19/2021 and 2/21/2021. How close are your predictions to the actual? Repeat with polynomial regression. (c) What is the daily rate of change on average of BTC closing prices based on your predictions obtained from regression on the data in the range of 12/15/2020 to 12/28/2020. What about for 2/2/2021 to 2/15/2021?
