I’m attempting to work with numpy’s lstsq. I’ve a trainX information set
t of the form:
and a trainY information set
ty of form:
The next assertion:
coff = np.linalg.lstsq(np.vstack([t,np.ones(t.shape)]).T,ty,rcond=None)
offers me the coefficient of form:
Now, with this mannequin, I wish to make queries on the check set
check of form :
If I do:
(coff[:-1] * check).sum(axis=1) + coff[-1] # mx + c
it throws an error
operands couldn't be broadcast along with shapes (8,1) (200,8)
Might somebody please clarify this error? How can I question on the check factors?
