pA: Bayes' Theorem.

Description

Estimate marginal and conditional probabilities using Bayes theorem.

Usage

pA(pAgivenB, pB, pAgivenNotB)
pB(pBgivenA, pA, pBgivenNotA)
pAgivenB(pBgivenA, pA, pB = NULL, pBgivenNotA = NULL)
pBgivenA(pAgivenB, pB, pA = NULL, pAgivenNotB = NULL)
pAgivenNotB(pAgivenB, pA, pB)
pBgivenNotA(pBgivenA, pA, pB)

Value

The requested marginal or conditional probability. One of:

• the marginal probability of A

• the marginal probability of B

• the conditional probability of A given B

• the conditional probability of B given A

• the conditional probability of A given NOT B

• the conditional probability of B given NOT A

Arguments

pAgivenNotB

The conditional probability of A given NOT B.

pBgivenA

The conditional probability of B given A.

pA

The marginal probability of event A.
