[ferret_users] weighted least square fit

Dear Ferreters,

I want to perform least square regression but with weighted values.

Suppose I am having three monthly time series A(x,y,t), B(x,y,t), C(x,y,t) and all are having equal time steps. I want to calculate regression in time but with weighted least square fit. For the mean estimates of these three time series I want to perform a weighted least squares fit to the monthly observations where the weights are chosen to equal the reciprocal variance of the these three gridded series to estimate errors at 1-sigma.

is it possible with ferret using go regresst ?

regards, saurabh
