compute_closest_wgps function

Find the closest data in subset to the original data

A function to compute the closest data in subset of data to the original data based on two attributes: vector and scalar (vector of size one).

compute_closest_wgps(a, b, c, d, sc, nthread)

Arguments

• a: Vector of the first attribute values for subset of data.
• b: Vector of the first attribute values for all data.
• c: Vector of the second attribute values for subset of data.
• d: Vector of size one for the second attribute value.
• sc: Scale parameter to give weight for two mentioned measurements.
• nthread: Number of available cores.

Returns

The function returns index of subset data that is closest to the original data sample.
