compute_D: Compute the matrix of distances D for kappa parameters

Description

Compute the matrix of distances D for kappa parameters

Usage

compute_D(Y = NULL, y_T = pi/4, y_D = (3 * pi)/4)

Value

a N x JI matrix containing the delta values for each data point in Y

Arguments

Y

(matrix) N x JI matrix of observed trajectories

y_T

(numeric) position in angles of the target

y_D

(numeric) position in angles of the distractor

Details

The function compute the distance of the Y-trajectories from the distractor and target points. This is an internal function, generally not to be called by the user.

Examples

## Generate a generic matrix Y of I = 5 individuals and J = 1 trajectories (N = 61)
I <- 5; N <- 61
y_T <- pi/4; y_D <- (3*pi)/4
Y <- matrix(stats::rnorm(n = N*I,mean = (y_T+y_D)/2,sd = 10),N,I)
DY <- compute_D(Y=Y,y_T=y_T,y_D=y_D)
