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 long-term 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
