using excel, Please Estimate the following regressions, including a constant term:

a) RCONS = f[RGDP, RGDP(t-1)] b) RCONS = f(RGDP, YEAR, T) c) RCONS = f(YEAR, T) d) RCONS = f(RGDP, WAR) e) RCONS = f(RGDP, RGDP2)

*please show steps on excel, thank you!*

I posted this so many time, it is not incomplete. Please solve the best you can.. Answer does not have to be right! PLEASE PROVIDE EXCEL WORK!!!
