Question

A linear regression model is said to be good when the r-squared value tends to 0, 1,-1 or 0.5

Answer 1

Answer:

Because the difference between values is very small that is why Linear regression model is good

Step-by-step explanation:

As we know that that the liner regression is a measure of variability of dependent variables.

it evaluates the scatter of the data . that what actual data is how far it is fitted from the regression line.

Value of R-squared is always between 0- 100% .

0% represents a that  no variation. so the mean of dependent variable predicts two things.

1. Dependent variable

2. Regression model

100% represents a model that explains all of the variation in the response variable around its mean.
