calculate_bias: Calculate bias weights

In mrfoliveira/STResampling-JDSA2020: Biased Resampling Strategies for Imbalanced Spatio-Temporal Forecasting

Description

Calculate bias weights

Usage

calculate_bias(form, dat, phi.control, thr.rel, time, site_id, ptype, ...)

Arguments

form	a formula describing the learning task
dat	A data frame with time and site_id columns.
phi.control	list of parameters as returned by function UBL::phi.control
thr.rel	a relevance threshold above which an observation is considered relevant.
time	the column name of the time-stamp
site_id	the name of the column containing location IDs
ptype	Type of spatio-temporal bias to calculate. Can include "orig", "addPhiLook", "addNoPhi"
...	Parameters to pass to sample_wts. Can include weight type (defaults to orig), alpha (defaults to 0.5), and location info (sites_sf or lat+lon+crs).

Value

Vector of bias weights
