what is linear least-squares approximation. could you show an example

Expert Solution

Least squares approximationi a method for estimating the true value of some quantity based on a consideration of errors in observations or measurements.

In this method we minimizes the sum of the squared distances (deviations) from the line to each observation is used to approximate a relationship that is assumed to be linear.

Example

In least square method we minimise as following type

A simple linear least squares regression of the heights (in feet) of a building on the number of stories in the building was performed using a random sample of 30 buildings. The associated ANOVA F statistic was 5.60. What is the P-value associated with this ANOVA F test? a.) greater than 0.10 b.) between 0.001 and 0.01 c.) between 0.01 and 0.025 d.) between 0.05 and 0.10 e.) between 0.025 and 0.05 f.) less than 0.001

Remind yourself about linear least squares fitting in section 3.2 of the lab manual, and then work through the following. In a particle physics experiment, there are six detectors at positions x = 10; 14; 18; 22; 26; and 30cm. These detectors measure the y positions of the trajectory of a charged particle to be 2.02; 2.26; 3.24; 3.33; 3.92; and 4.03 cm, respectively (i.e., the first position is (10,2.02), the second position is (14,2.26), and so on). The errors...
