Description of the variables in the dataset.
| Variable | Type | Description |
|---|---|---|
| Tournament_Year | Numeric | Yearly season |
| Tournament_Order | Ordinal | Chronological order of tournaments within a season (i.e., smaller numbers took placer earlier in the season) |
| Permanent_Tournament_Number | Numeric | Identification number that is unique to that tournament, regardless of the sponsor/name of the tournament that may change over the years |
| Course_Number | Numeric | Course number that does not change over time (i.e., different tournaments may be played on the same course) |
| Player_Number | Numeric | Player identification number. Does not change over the years |
| Round_Number | Numeric | Round number. PGA Tour tournaments generally have four rounds |
| Event_Name | Numeric | Name of the tournament |
| Course_Name | Text | Name of the course in which the tournament took place |
| Interview_Text | Text | The integral text of the interview |
| Number_Of_Answers | Numeric | Number of answers provided by Tiger Woods during the Q&A section |
| Link | Text | Link to the original document (redirecting on ASAP Transcription website) |
| Response_Negative | Numeric | The negative score computed on Tiger Woods’ responses |
| Response_Positive | Numeric | The positive score computed on Tiger Woods’ responses |
| Response_Sentiment | Numeric | The subtraction between the positive and the negative scores computed on Tiger Woods’ responses |
| Round_Score | Numeric | Number of strokes of the round |
| End_of_Round_Pos_numeric_ | Ordinal | Player's rank in the round (i.e., 1 means he is leading the tournament, 2 means he is the runner-up, etc.) |
| Total_Holes_Over_Par1 | Numeric | Number of holes in the round in which the player scored bogey or worse in the round |
| Birdies | Numeric | Number of birdies in the round |
| Birdies_Rank | Ordinal | Players' rank in number of birdies in the round (i.e., 1 means he was the player with the highest number of birdies in the round) |
| Bogey_Avoidance_Rank | Ordinal | Player's rank in terms of the number of holes in which the player saved a situation of bogey in the round |
| Driving_Distance_Rank2 | Ordinal | Player's rank in driving distance in the round |
| Driving_Accuracy_Rank | Ordinal | Player's rank in driving accuracy in the round |
| GIR_Rank3 | Ordinal | Player's rank in number of greens in regulation in the round |
| Scrambling_Rank4 | Ordinal | Player's rank in scrambling in the round (i.e., ability to recover from difficult situations) |
| Distance_to_leader_strokes | Numeric | Distance in strokes to the interim leader at the end of the round (i.e., if Tiger is trailing by two shots, it takes value 2; if Tiger is leading, the variable takes value 0) |
| Distance_to_leader_ranks | Numeric | Distance in ranks to the interim leader at the end of the round (i.e., if Tiger is in rank 3, it takes value 2; if Tiger is leading, it takes value 0) |
| Ranks_gained | Numeric | Equal to the rank at the end of Roundn minus the rank at the end of Roundn-1. For instance, if Tiger had a position 3 at the end of Roundn and 5 at the end of Roundn-1, the variable's value is −2. It takes missing values for round 1 |
| Strokes_gained_v_a_v_Leader | Numeric | Equal to distance to the leader (in strokes) at the end of Roundn minus distance to the leader (in strokes) at the end of Roundn-1. It takes missing values for round 1 |
| Distance_to_runner_up_strokes_ | Numeric | Distance in strokes to the interim runner-up at the end of the round. For instance, if Tiger is leading by two shots, the variable should take value 2; if Tiger is co-leading, the variable should take value 0; if Tiger is neither leading nor co-leading, it takes missing value. |
| Strokes_gained_v_a_v_Runner_up | Numeric | Distance in strokes to runner-up at the end of Roundn minus distance to runner-up at the end of Roundn-1. Note that this variable should have a missing value for observations of round 1. Note that this variable should have a missing value when Tiger is not leading. |
| Minor Injury | Categorical {1; 0} | Tiger had a minor injury when he entered the event |
| Major_injury_surgery | Categorical {1; 0} | Tiger Woods had a major injury when he entered the event |
| Personal_issues | Categorical {1; 0} | Tiger Woods had personal issues when he entered the event |
| Major | Categorical {1; 0} | Takes value 1 if tournament is a major (i.e., prestigious) |
| Prize_Money | Numeric | Prize money of the tournament |
| SoF | Numeric | Strength of the field of players in the tournament (i.e., the higher the number, the more competitive is the field) |
| OWGR | Numeric | OWGR of Tiger at the moment of the observation |
1
In golf, par is the predetermined number of strokes that a proficient golfer should require to complete a hole. Bogey is a score of one stroke more than par. Birdie is a score of one stroke fewer than par. For instance, if in a par-4 hole a player scored 3, he birdied the hole; if he scored 4, he made par in the hole; if he scored 5, he bogeyed the hole.
2
A drive is the long-distance shot intended to move the ball a great distance down the fairway towards the green, in which the target hole is located.
3
The green is the area of specially prepared grass around the hole. A player hits a green “in regulation” if the ball is on the surface of the green and the number of strokes taken is at least two fewer than par (i.e., second stroke in a par-4 hole).
4
When a player misses the green in regulation, but still makes par or birdie on a hole.
