Question

5. Determine the data type of the value "709.012"​

Answer 1

Explanation:

The variable of interest (dependent variable, yi) is

hard to measure.

• There are “easy to measure” variables (predictor/

independent) that are related to the variable of

interest, labeled x1i , x2i,.....xmi

We measure the y and the x’s for a sample and use

this sample to fit a model.

Once the model is fitted, we can then just measure the

x’s, and get an estimate of y without measuring it
