Which estimating technique uses a statistical relationship between historical data and other variables (e. g., square footage in construction, lines of code in software development) to calculate an estimate for scope, cost and duration?

Parametric estimating

Explanation:

It is a calculation technique in which an algorithm is used to calculate the cost or duration based on historical data and project parameters.

The parametric estimation uses a statistical relationship between historical data and other variables (eg, square meters of construction) to calculate a variable of the parameters of an activity such as cost, budget and duration.
