Question

Please answer with detailed explanation.

Answer the following with TRUE or FALSE. It is good practice to justify your answer (a) The absolute difference in the SS E values may be used to assess which of the models fits better (b) If factor A effects are present, we would expect there to be a significant difference in at least one pair-wise comparison of factor A means. (c) The maximum value of a conditional or partial R2 is 1. (d) The estimated value of σ, does not depend on the model chosen.

Answer 1

ANSWER:

Answer the following with TRUE or FALSE:

(a) To absolute difference in the SSE:

We have to obtained the this statement is true or false is ,

Here,

The absolute difference in the SSE values may be used to assess which of the models fits better .

This statement is TRUE.

(b) If factors A effects are present :

If factors A effects are present ,we would expect there ,

This statement is TRUE.

It is also known as hypothesis. We have to define different conditions of hypothesis.

(c) The maximum value of a conditional :

The correlation values between -1 to +1 .so maximum value is 1.

So this statement is TRUE.

(d) The estimated value of sigma^2:

The estimate value of sigma^2 ,does not depend on the model is ,

It is a FALSE statement.

When we are estimating a parameter definitely , the concern variable should follows predefined model.
