EC_T: Compute the Euler characteristic for a given field

Description

It computes the Euler characteristic (EC) of a given field above specified thresholds over a specified search area.

Usage

EC_T(ck, Ts, THETA)

Arguments

ck

Vector of thresholds defining the excursions sets with respect to which the ECs are computed.

Ts

Vector of values of the field for each grid point in THETA.

THETA

A vector or matrix of grid values for the nuisance parameter with respect to which the search is performed.

Value

Returns a vector of EC values with respect to the thresholds specified in ck.
