Study guide: Exam MAS-I
You are given the following daily temperature readings, which are modeled as a function of two independent variables:
| Observation | Temperature | X_1 |
X_2 |
|---|---|---|---|
| 1 | 5 | 4 | 6 |
| 2 | 10 | 8 | 2 |
- The data set consists of only these two observations.
- The first principal component loading for
X_1,\phi_{11}, is 0.750. - The first principal component loading for
X_2,\phi_{21}, is positive.
Calculate the principal component score for Observation 1.
- A) Less than 0.00
- B) At least 0.00, but less than 0.20
- C) At least 0.20, but less than 0.40
- D) At least 0.40, but less than 0.60
