dermesser / accum.R

Created July 20, 2022 22:06

Here you will develop "d,p,q,r" functions for a certain distribution family. We'll call the family "accum" for "accumulate." The setting is that of repeatedly rolling a pair of dice. The random variable X is the number of rolls needed to achieve an accumulated total of at least k dots. So for instance the support of X ranges from ceiling(k/12) t…


	# P(dots == n) for k dice
	dkdice <- function(n, k=2) {
	if (k == 1) {
	if (n >= 1 && n <= 6) {
	return(1/6)
	} else {
	return(0);
	}
	} else if (k < 1) {

OFDM encoding example in Julia. OFDM is using Fourier transforms to achieve higher spectral efficiency when encoding digital data for e.g. optical fiber transmission.
