Question
Suppose we fit the simple linear regression model
and get the estimated regression function
. What population characteristic of Y does estimate?
the mean of Y for a given value of x
the proportion of the population above the mean for a given value of x
the geometric mean of Y for a given value of x
the total variability in Y a given value of x
the standard deviation of Y for a given value of x
the mean of Y for a given value of x
the proportion of the population above the mean for a given value of x
the geometric mean of Y for a given value of x
the total variability in Y a given value of x
the standard deviation of Y for a given value of x
Explanation / Answer
Y-hat estimates :
the mean of Y for a given value of x
the mean of Y for a given value of x
