What is the relation between Sample and population regression function?
The sample regression function is a statistical approximation to the population regression function.
What is a linear regression?
Suppose you have n objects and for each object you have observations for k+1 variables, X1, X2, ... , Xk and Y.Then a linear regression is an equation of the form E(y) = a + b1x1 + b2x2 + ... + bkxk where E(y) is the expected value of the variable Y when Xi has the value xi; and where a, and b1, b2, ... , bk are constants.

What is a linear object?
an object which moves linearly is called a linear object.
What type of motion occurs when an object spins around an axis without altering its linear position?
Rotational motion.

What is the rate of motion of an object in a linear object?
That is the object's 'speed'.
What is the object modeling?
Object modeling is most often used in reference to computing applications. It usually refers to the collection of objects that a program manipulates and examines certain parts of its system.
What is the rate of motion of an object in linear motion?
That is the object's 'speed'.
What is the rate of motion of an object in a linear motion?
That is the object's 'speed'.
Formula fo linear velocity?
The formula for velocity is ds/dt where s (which is a function of time) is the position vector of the object at time t, and d/dt represents the derivative with regard to time.The formula for average velocity is (final position vector - starting position vector)/time.
