Data Requirements Need 24 years/locations/sites/trials Need at least 3 replications Need at least 10 treatments Grain yield (yield value of any kind) NDVI 

Need to discuss the value of good tables: Digit precision needed, footnotes, (use examples)  
ADDED Data OSU LongTerm Experiments Experiment 502, Lahoma, Oklahoma Experiment 222, Stillwater, Oklahoma


Class Project and Programs (Metric units) 1. Shawntel Ervin (February 5, 2015) 2. MSE vs yield (February 26, 2015) (SAS file without CV) 3. Excel File MSE_Yield April 8, 2015 4. Class Publication (4/21/2015) 5. E502Check 6. Class project, program, 4/21/2015 (3D surface response) Class PROJECT: Objectives: 1. To determine the frequency for combining year to year data from longterm experiments 2. To determine the relationship between MSE and yield level Literature Review: Need to partition sections HOMEWORK #2 1. Run a 3D surface response model (502 and 222) for Mgha = year*CV (need regression output and graphic output). To do this you will need to compute CV, or retrieve it from our CLASS PROJECT FILE. 2. Provide a written interpretration for the results Homework #3 1. Construct contrasts for the following comparisons using data from Experiment 502 a. N rate linear b. N rate quadratic c. High P rate (fixed N and K) versus 0P rate d. High K rate (fixed N and P) versus 0K rate Homework #4 a. Using our class data set, construct a linear plateau model for (222 and 502 individually) MSE (y) versus Yield (x) b. report the "joint" and a functional equation (that would describe the model) c. Was the R2 improved over that of a linear model? Why or why not? Homework #5 Class project. Prepare on one sheet of paper, a project you hope to carry out, into the future. This is the same project as your presentation to the class. Items to help you include the abstract below and ASA Abstract Hand Planter 2015 

3. To determine the differences in these
relationships when PROC GLM and PROC MIXED are used http://www.ats.ucla.edu/stat/sas/library/GLMvsMIXED_os.htm PROC GLM vs PROC MIXED
