ImpactMG {CompoundEvents}

Impacts under droughts and hot extremes

Description

Use the meta-Gaussian model to construct conditional distributions of the impact variable (Y) given drought and hot conditions P(Y|PRC,TEM).

Usage

ImpactMG(PRC,TEM,Y,u0)

Arguments

PRC

Precipitation or drought indicator corresponding to the impact variable Y

TEM

Temperature or heat indicator corresponding to the impact variable Y

Y

Impact variable (e.g., Crop yield)

u0

Initial condition of (PRC,TEM)

Value

A vector of conditional mean and variance evaluated at u0
