mincontrast_st: Minimum constrast spatio-temporal estimation

In realTimeSurv: Real Time Disease Surveillance Using Geospatial Statistical Modelling

Description

A wrapper to the function lgcp::minimum.contrast.spatiotemporal

Usage

mincontrast_st(data, covariates, boundary, pop.var = "popdens")

Arguments

data	A data frame consisting of columns x, y, and t, which are two spatial coordinates and time point respectively.
covariates	A spatialPolygonsDataFrame covering the area of interest with the population density column named popdens
boundary	A spatialPolygonsDataFrame of the boundary of the area of interest.
pop.var	Name of the population density variable

Details

mincontrast_st provides a simplified wrapper to the function lgcp::minimum.contrast.spatiotemporal. For more details see help(lgcp::minimum.contrast.spatiotemporal).

Value

Returned values are the minimum contrast estimates of phi, sigma^2 and theta, as well as the overall squared discrepancy between the parametric and nonparametric forms of the spatial function used corresponding to these estimates.
