Methods
(static) valuesOk(x, y) → {boolean}
Checks if probabilities are valid (i.e. between 0 and 1)
Parameters:

x |
number | probability |
y |
number | probability |
- Source:
Returns:
true of x and y are valid probabilities
- Type
- boolean
(static) XandNotY(x, y) → {number}
Calculates probability of independent X and Y - X occurs but not Y.
Parameters:

y |
number | probability of Y (0 <= y <= 1) |
- Source:
Returns:
probability of X occuring but not Y
- Type
- number
(static) XandY(x, y) → {number}
Calculates probability of independent X and Y occuring together.
Parameters:
