Answer
We know that R^2 is given as
R^2 =1 - (SSE/SST)
where SSE is sum of square residual and SST is sum of squares total
when SSE = 0, we get
R^2 = 1- (0/SST)
= 1- 0
= 1
So, option C is correct
Answer is R^2 = 1

Theory: A vector with nonnegative entries is called a probability vector if the sum of its entries is 1. A square matrix is called right stochastic matrix if its rows are probability vectors; a square matrix is called a left stochastic matrix if its columns are probability vectors; and a square matrix is called a doubly stochastic matrix if both the rows and the columns are probability vectors. **Write a MATLAB function function [S1,S2,P]=stochastic(A) which accepts a square matrix A...

In information theory Shannon entropy is defined by H(x) = -Sum(P(x)*log(P(x)) where P is probability mass function of random variable x, and log to base 2. Given loaded die with P(6)=0.5 and P(1)=P(2)=P(3)=P(4)=P(5), compute entropy of observed rolls 654266. Note: To answer the question you do not need to know any more information about Shannon entropy.
