Question

How to perform Matlab for the biased coin toss

by Apr 21, 2018 2:22PM PDT

Let the bias be the probability of turning up a head and denoted by the parameter q.

If we use a coin with the bias specified by q to conduct a coin flipping process d times, the outcome will be a sequence of heads and tails.

Then the probability - where nH is the number of heads turned up during d trials.

Now using such a simulated coin with q = ½ to conduct the experiments based on a sequence of outcomes generated by the random generator from computer.

For example, if the number generated by the random generator is less than 1/2, it assigned to be 0; otherwise, it will be assigned 1.

I would like to perform the Matlab programming with certain parameters for the Pattern Recognition (such as Binomial Distribution) as below -

(1) d = 100 and n =100 using a simulated coin with q = ¼ and ½.

(2) d = 10 and n =1000 using a simulated coin with q = ¼ and ½.

(3) d = 100 and n = 1000 using a simulated coin with q = ¼ and ½.

Kindly please provide your opinion and suggestion thus I will be able to improve my computing skills.

(The result of the execution from program will be drawn into histogram on the PowerPoint)

Matlab Programming Method - I get some errors for my coding sample as below


(1)

x = rand(0,1);
if(x<0.25),
toss = 0; %Head
else
toss = 1; %Tail
end
n = 100;
d = 100;
hist(y,0:n)

x = rand(0,1);
if(x<0.5),
toss = 0; %Head
else
toss = 1; %Tail
end
n = 100;
d = 100;
hist(y,0:n)

For that, find coding forums.
