Estimate at completion (EAC/ETC/VAC) API

Forecast project cost with the standard PMBOK EAC family — method 'cpi': EAC = BAC/CPI; 'cpi-spi': EAC = AC + (BAC-EV)/(CPI·SPI); 'remaining': EAC = AC + (BAC-EV) — plus ETC = EAC-AC, VAC = BAC-EAC, projected overrun, and a breakdown. Answers 'what will this project cost at completion','estimate to complete','what is my variance at completion','will I overrun the budget'.
