Set a random seed, and then compute the loocv errors that result from fitting the following four models using least squares: i. y = β0 + β1x + ε ii. y = β0 + β1x + β2x2 + ε iii. y = β0 + β1x + β2x2 + β3x3 +ε iv. y = β0 + β1x +β2x2 + β3x3 + β4x4 +ε. note you may find it to use the data. frame() function to create a single data set containing both x and y .

answer: i don't understand it

step-by-step explanation: sorry

the answer is ! ?

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
