Arguments

M	DP base measure constant (> 0)
g0.alpha, g0.beta	parameters of Beta base measure of DP
k1.theta	prior parameter for polynomial corresponding to rescaled time (propto exp(-k1.theta*k1*log(k1)))
k2.theta	prior parameter for polynomial corresponding to rescaled frequency (propto exp(-k2.theta*k2*log(k2)))
tau.alpha, tau.beta	prior parameters for tau (inverse gamma)
k1max	upper bound of the degrees of Bernstein polynomial corresponding to rescaled time (for pre-computation of basis functions)
k2max	upper bound of the degrees of Bernstein polynomial corresponding to rescaled frequency (for pre-computation of basis functions)
L	number of terms in fast DP approximation
bernstein1_l, bernstein1_r	left and right truncation of Bernstein polynomial basis functions for rescaled time, 0<=bernstein1_l<bernstein1_r<=1
bernstein2_l, bernstein2_r	left and right truncation of Bernstein polynomial basis functions for rescaled frequency, 0<=bernstein2_l<bernstein2_r<=1

Value
