In rts2: Real-Time Disease Surveillance

Disaggregate regional means to fine grid, preserving aggregate means

Description

Disaggregate regional means to fine grid, preserving aggregate means

Usage

disaggregate_covariate(
  x_r,
  W,
  adj,
  pop = NULL,
  lambda_smooth = 1,
  lambda_ridge = 1e-04
)

Arguments

x_r	length m vector of regional means (or pop-weighted means)
W	m x n aggregation matrix (1 if cell in region, 0 otherwise)
adj	n x n adjacency matrix
pop	optional length n population vector; if provided, preserves population-weighted means rather than simple means
lambda_smooth	weight on spatial smoothness
lambda_ridge	small ridge for numerical stability (needed because L is singular)

Value

A list
