Description Usage Arguments Examples
The generated data Y ~ Bernoulli(p) is the image intensity, where the success probability p is determined by whether the location X, given by polar coords (r,θ), is inside the boundary or not.
1  par2obs(m, pi.in, pi.out, design, center, gamma.fun)

m 
m * m observations will be generated over the unit square centered at (0,0). 
pi.in 
The success probability, P(Y_i = 1), where Y_i is intensity of pixel i if the location is inside the boundary. 
pi.out 
The success probability, P(Y_i = 1), where Y_i is intensity of pixel i if the location is outside the boundary. 
design 
Taking values: 'D' for deterministic (equallyspaced grid) design, 'U' for completely uniformly random, or 'J' for jitteredly random design. 
center 
a twodimensional vector of Euclidean coordinates (x,y) of the reference point. 
gamma.fun 
The function to generate boundaries, see ellipse or triangle2.
