why is it called ratio in a linear regression model which factor is used to calculate coefficient in a linear regression model? why is r square called correlation why is the coefficient an r square what is r square what is the square of the correlation why is the ratio called r square why is r square based on correlational analysis? which of the following is the square of the correlation of r square? if the total variation is the correlation between a random variable, then the ratio of residuals is called? explain why the correlation between two variable is called the ratio which of the following is the explanation for the square of the relation between linear regression model what is the relationship between the coefficient of variation and the residuals when a coefficient is r square the coefficient of correlation is how is the relationship between the coefficient and the correlation of residuals calculated in a regression model? what is r square in regression which is true of correlation why is r square a correlation what makes the coefficient r square define r square in regression
