CE 506 Homework Fall 2005
- homework 1. read chapter 10 except sections 10.10 (nonlinear),
and 10.13 ("conditional" equations). make a least squares fit of
a line to the data points (x,y) = (-1,1),(3,3),(6,4),(8,4). the
y coordinate is the observation, the x coordinate is a constant.
(this is the famous regression problem). show the parameter estimates,
the residuals, and the adjusted observations. do again but weight the
four observations by 1,4,1,1, respectively. due thursday, 8 sept.
- homework 2. read chapter 11 on level networks, and chapter 17,
sections 1-5. do the 2 problems described here.
due tuesday, 20 september.
- homework 3. read section 10.10 & compare with class derivation.
read appendix c. do problems c-1, c-2, c-5, and do the angle figure
adjustment given here. due friday,
30 sept.
- homework 4. read chapters 13 & 14 on 2d network adjustment,
do problems from the text: 13.4 and 14.6. for both problems ignore
the specific results requested and supply: parameter estimates,
residuals, adjusted observations, along with usual detailed
description of your approach, condition equations, matrices,
program listings, etc. due friday 14 october.
(don't put this off too long!)
- homework 5. position determination by least squares solution
of gps pseudoranges. get this writeup
and get this data & code hints.
assigned thursday, 20th, due in a week.
- homework 6. adjustment of gps baselines. read text, section
16.8, do problem 16.3. make the global chi-squared test on the
quadratic form of the residuals (2-tailed, at alpha = 0.05). then make a 99
percent confidence region for XY of point B, and a 99 percent confidence
interval for Z of point B. due thursday, 17 november.
- homework 7. book report
- homework 8. THERE IS NO HOMEWORK 8. just study the general least squares
example problems that were given in class (line fit and circle fit with
both coordinates observed).
