for provided plays. Returns the data with probabilities of winning the game. The following columns must be present: receive_h2_ko (1 if game is in 1st half and possession team will receive 2nd half kickoff, 0 otherwise), home_team, posteam, half_seconds_remaining, game_seconds_remaining, spread_line (how many points home team was favored by), down, ydstogo, yardline_100, posteam_timeouts_remaining, defteam_timeouts_remaining

## Value

The original pbp_data with the following columns appended to it:

- wp
win probability.

- vegas_wp
win probability taking into account pre-game spread.

## Details

Computes win probability for provided plays. Returns the data with spread and non-spread-adjusted win probabilities. The following columns must be present:

receive_2h_ko (1 if game is in 1st half and possession team will receive 2nd half kickoff, 0 otherwise)

score_differential

home_team

posteam

half_seconds_remaining

game_seconds_remaining

spread_line (how many points home team was favored by)

down

ydstogo

yardline_100

posteam_timeouts_remaining

defteam_timeouts_remaining
