Kobe's track record

In the kobe data frame, every row records a shot taken by Kobe Bryant. If he hit the shot (made a basket), a hit, H, is recorded in the column named basket, otherwise a miss, M, is recorded.

Just looking at the string of hits and misses, it can be difficult to gauge whether or not it seems like Kobe was shooting with a hot hand. One way we can approach this is by considering the belief that hot hand shooters tend to go on shooting streaks. For this lab, we define the length of a shooting streak to be the number of consecutive baskets made until a miss occurs.

For example, in Game 1 Kobe had the following sequence of hits and misses from his nine shot attempts in the first quarter:
H M | M | H H M | M | M | M.

  • Take a look at the names of the variables in kobe. (The data frame is already loaded.)
  • Verify Kobe's hit/miss track record by printing the first nine observations in the basket variable. Compare the output to the sequence shown above.
