How to Calculate the Pearson Correlation coefficient between the bits of a 20 bit hash value?

I am working on testing the uniformity of the hash functions.For that i need to find how uniformaly the bits were distributed in the 20 bit hash value.

There are examples to find the correlation coefficient between two values X and Y. I don't know how to calculate the correlation between the bits of a hash value.

The hash value will be like hash= 29600128950574211287.

Thanks,

Elakkiya

Go through the following documentation link to find about " corrcoef ", which can be used to calculate Pearson Correlation Coefficient.

n=input("enter the number of observations");

sumx=0;

sumy=0;

sumxx=0;

sumyy=0;

sumxy=0;

for k=1:n

x(k)=fprintf("enter the value of x(%d)":k);

x(k)=input("enter the value of x(%d)":k);

y(k)=fprintf*("enter the value of y(%d)"):k);

y(k)=input("enter the value of x(%d)":k);

sumx=sumx+x(k);

sumy=sumy+y(k);

sumxy=sumxy+(x(k)*y(k));

sumxx=sumxx+(x(k)*x(k));

sumyy=sumyy+(y(k)*y(k));

end

kp=((n*sumxy)-sumx*sumy)/(sqrt((n*sumxx)-(sumx*sumx)))*(sqrt((n*sumyy)-(sumy*sumy)))

disp=("kp");
