Converts US or Decimal odds and wager size to potential win quantity. Note that by using the default value of 1 for wager size, these two functions effectively convert from US/decimal odds to fractional odds. Example, US2Win(-120,120) = 100, or US2Win(-110) ? 0.90909.

Converts US or Decimal odds, wager size, and result (where “WIN”, “W”, or “1”, corresponds to a win; “LOSS”, “L”, or -1 corresponds to a loss; and “PUSH”, “P”, or 0 corresponds to a push). Example, US2Res(-120,120,”P”) = 0, or =US2Res(-110, 200,”Win”) ? 181.82.

Calculates Kelly criterion utility for a given bankroll (expressed in percent terms) and Kelly multiplier. Example: KUtil(1.05, 0.5) would yield half-Kelly utility for a bankroll of 105% of initial.

The inverse Kelly Utility function. Calculates the bankroll (expressed in percent terms) implied by a given Kelly criterion utility and Kelly multiplier. Example: InvKutil(KUtil(X, KellyMult),KellyMult) would just equal X (provided X > 0).

Calculates single bet Kelly stake given an expected win probability, paypout odds, and optional Kelly Multiplier. If the “Decimal Odds Flag” isn’t set or is set to FALSE, then the function will use a “best guess” as to whether the odds specified are US or decimal-style (if absolute value < 100, it will assume decimal). Setting the flag to TRUE will cause the function to always assume decimal-style odds (this could be helpful when using decimal-style odds at very high payout levels).

(array function) Returns an array of likelihoods such that the ith element of the output array (i ? [0, 1, 2, …, n], where n = the number of probabilities in the input range) corresponds to to the likelihood of exactly n-i wins and i losses given the n event win probabilities in the input range. Example: if cells (A1, A2, A3) = (75%, 70%, 65%), and cells B1, B2, B3, and B4 were set to the array formula {=P2L(A1:A3)}, cell B1 would correspond to the probability of 3 wins and 0 losses (~ 34.13%), cell B the probability of 2 wins and 1 loss (~44.38%), B3 the probability of 1 win and 2 losses (~18.88%), and B4 the probability of 0 wins and 3 losses (2.63%). Note that this function may be rather slow to calculate for large input sets.

(array function) Returns a 2-D array of every possible combination of of the specified size of the input range. Example: if cells (A1, A2, A3, A4, A5) = (“A”, “B”, “C”, “D”, “E”), then {=ENUMCOMBIN(A1:A5, 2)} would return the 6-row, 2-column array of {(“A”,”B”),(“A”,”C”),(“A”,”D”),(“B”,”C”),(“B”,”D”),(“C”,”D”)}. Note that this function may be rather slow to calculate for large input sets. EnumComin is short for “Enumerate Combinations”.

Calculates the inverse logit function of x where invlg(x) is defined as invlg(x) = Exp(x) / (1 + Exp(x)).

Calculate sportsbook equivalent US or Decimal odds given US or Decimal Matckbook exchange odds and commission. This references a commission structure where the player pays a set percentage of the lesser of risk or win irrespective of bet outcome. Example: MB2US(-110, 1%) would refer to the sportsbook equivalent odds of betting at -110 given 1% Matchbook commission (~-112.12).

Array function. Takes a range of betting odds (US odds are the default, but will take decimal odds if the Decimal Odds Flag argument) is set to TRUE, an optional range of wager quantities (if not provided then 1 unit per wager is assumed), a range of outcomes (1 or a string starting with ‘W’ for a win, -1 or a string starting with ‘L’ for a loss, anything else for a push/no action), and a range of expected edges (defaults to 0). Returns an array with the following values:

1. Number of Non-Pushed Bets
2. Number of Wins
