Question

The weight used in the least-square method is a function of __________

(a) twice the distance between the vertex and the centroid of the cells

(b) square of the distance between the vertex and the centroid of the cells

(c) inverse of the distance between the vertex and the centroid of the cells

(d) the distance between the vertex and the centroid of the cells

Answer 1

Correct choice is (c) inverse of the distance between the vertex and the centroid of the cells

Easy explanation: Generally, the weight used is based on the distances. We can choose it to be the inverse of the distance between the vertex and the cell centroids. Mostly, the weight is a function of the distance between the vertex and the cell centroids.
