...on the nonlinearity of the model used. Are there any developed routines in R ? to: 1) calculate the maximum intrinsic curvature 2) maximum parameter affecting curvature 3) plot the two dimensional cross sections of confidence regions (for different alpha values) of the model parameters Regards, Ivone Figueiredo [[alternate HTML version deleted]]

...xample Suppose I have a vector a=c(v_1,...,v_p)=c(0.5343909, -0.7784353, -0.0568370, 1.8772838, -1.3183407, 0.8227418,...) I want to compute density(v_i, v_j) for every pair of entries (i,j) (i!=j) in a. The joint bivariate distribution is known to be the same for each pair. Thanks a lot!
