Help with Weighted Regression in Matlab
I need to weight the regression I am performing on a data file. I am not using all the numbers in the file. Here are my variables:
Y = data([1:8,9:16,73:80,137:144,225:232,265:272,327:334,305:312,353:360,361:368,425:432,489:496,577:584,617:6 24,641:648,657:664],1)
X has the same bracketed first term, and the second term is [6,63,181,157,203,194]

I have eight different weights I want to give, one weight corresponding to two different sets of 8 rows (e.g. 1:8 and 353:360). How can I assign the weights appropriately and then regress(Y,X,weights) ? I messed around with for and if loops, but I couldn't figure it out.
