Root-Mean-Square(RMS) Difference
Dear R users,
I am comparing two data sets (CO2 observation vs. CO2 simulation, during
1993-2002).
In order to do it I am calculating Root-Mean-Square(RMS) difference
with following formula:
> sqrt(sum((observed_residual - simulated_residual)^2)/n) # 'n' is number of
observations
Residuals are computed by fitting a harmonic function on both the data:
>testfit<-lm(co2obs~1+time+I(time^2)+sin(2*pi*time)+cos(2*pi*time)+sin(4*pi*time)+cos(4*pi*time)+sin(6*pi*time)+cos(6*pi*time)+sin(8*pi*time)+cos(8*pi*time),data=file)
