Question

If two regression coefficient 4 and 16 the percentage of unexplained variation is

Answer 1

Answer:

36

Step-by-step explanation:

Correlation, r, is a measure of linear association between two variables. Coefficient of determination, r^2, is a measure of how much of the variability in one variable can be "explained by" variation in the other.

r^2=expainrd vaiance/total variance

1-r^2=1 - (expainrd vaiance/total variance )

       = Unexpainrd vaiance/total variance

we know : r^2=Bxy*Byx  

given Bxy=4 & Byx=16

r^2= 4*16  

    =64

1-r^2 = 1- 64/100

        =  100-64 /100

        =36%

        = un explained variance
