When the sum of square residual is 0, R2 is
Need more information to answer this question.
a. 0
b. 0.5
c. 1
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...

HELP!! I need an answer ASAP Question: When is an intangible asset that is to be amortized considered as having a residual value other than $0? note: b. Provide your answer using complete statements and using proper grammar, punctuation, etc. c. Provide a proper reference from FASB Codification in proper form: xxx-xx-xx-xx or xxx-xx-xx
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.

answer both please
0 41 A perfectly vertical scatter plot relationship between Y and X Question 18 (3 points) Since increasing the number of variables increases R2 why not include every variable in the regression equation? 1) Yes, you can include as many significant variables as you wish since computation power is the only limitation on regression modeling. 2) No, since adding more variables will eventually increase the degrees of freedom in the numerator of the F statistic and the...
I know that the sum of square of normal random variables follow a chi-square distribution. But when I learn how to do a goodness-fit test I don't know why the ratio of (O-E)^2/E follows a chi-square. I tried to square root of it first so that I might get something looks like a normal, but my new question arises : why (O-E)/sqrt(E) follows a normal-distribution? I know from sampling distribution that if the sample is from the same distribution as...
