Normalising constant for kernels in FKSUM
Computes the normalising constant for kernels implemented in the FKSUM package, to convert kernel with arbitrary beta coefficients to one which is a probability density. That is the kernel with coefficients equal to beta/norm_const_beta(beta) has unit integral
numeric vector of positive coefficients.
