The coefficient of determination R2 in a simple regression model -
ans -> a) measures the proportion of variation in the response variable that is explained by the predictor variable
Since
coefficient of determination R2 = variation in the response variable that is explained by the predictor variable / total variation

Which of the following statements is false about the coefficient of determination r2
Which of the following statements are not correct? The
coefficient of determination, denoted by r^2 is interpreted as the
proportion of observed y variation that cannot be explained by the
simple linear regression model. The higher the value of the
coefficient of determination, the more successful is the simple
linear regression model in explaining y variation. If the
coefficient of determination is small, an analyst will usually want
to search for an alternative model (either a nonlinear model or a...

In regression analysis, if you know that the coefficient of determination is R2 = 0.40 when X1 is used to predict Y, and R2 = 0.42 when X2 is used to predict Y, then it should be possible to determine the possible range of R2 values when both X1 and X2 are used to predict Y. What is the possible range for R2 in the two-predictor model?
