B. Parametric estimating
C. Analogous estimating
D. PERT

Explanation:
Parametric estimating uses statistical relationships between historical data and other variables to calculate an estimate for activity parameters such as cost, budget, and duration. The activity durations then are determined quantitatively by multiplying the quantity
of work to be performed by the labor hours per unit of work. This technique can produce higher levels of accuracy depending on the reliability of the data in the model.
