Dear Manash Barthakur,

PW : it is an abbreviation to say:

It is the projection on the space W.

It is related to elementary linear algebra.

In your case, I assumed the data of the (fitting curve) projected into a line

Y =ax + b in a vector space W (may be the real plane itself).

Best regards

Manash Barthakur

Thanking you
