Reliability of Product Term.

Estimate the reliability of a product term (assuming the individual indices are centered for the computation of the product term).

Usage

reliabilityOfProductTerm(x, y, reliabilityX, reliabilityY)

Arguments

x

Vector of one variable that is used in the computation of the product term.

y

Vector of second variable that is used in the computation of the product term.

reliabilityX

The reliability of the x variable.

reliabilityY

The reliability of the y variable.

Value

Reliability of the product term that is computed from the multiplication of x and y.

Details
