The planned schedule of topics and events may need to be adjusted throughout the course. The online syllabus above will always have the most current schedule and course materials.
This course will illustrate the uses of generalized linear models for predicting univariate and multivariate outcomes. The course is organized to take participants through each of the cumulative steps in a statistical analysis: deciding which type of model is appropriate, creating predictor variables, building models to evaluate unique effects of predictors, and interpreting and presenting empirical findings. Class time will be devoted primarily to lectures and examples. Lecture materials will be available for download at the website above no later than the day prior to class, or else paper copies can be requested. Video recordings of the class lectures will also be available online but are not intended to take the place of class attendance (either in person or via zoom). Readings will be assigned for each specific topic as needed; the initial list of readings below may be updated later. There will be no required sessions held outside the regular class time noted above. However, because the course will have an applied focus requiring the use of statistical software, participants are encouraged to attend groupbased office hours, in which multiple participants will have opportunities to work on course assignments simultaneously and receive immediate assistance. Participants should be comfortable with general linear models (e.g., analysis of variance and linear regression) prior to enrolling in this course. Auditors and visitors are always welcome.
Participants will have the opportunity to earn up to 100 total points in this course. Up to 86 points can be earned from homework assignments (approximately 6 in total)—these will be graded for accuracy. Up to 14 points may be earned from submitting outsideofclass formative assessments (approximately 7 in total); these will be graded on effort only—incorrect answers will not be penalized. Please note there will also be an opportunity to earn up to 3 points of extra credit (labeled as homework 0; see the above syllabus). There may be other opportunities to earn extra credit at the instructor's discretion.
REVISION for Weeks 1116: Given the transition to online instruction and loss of one academic week, the coursework has been revised as follows: Participants will now have the opportunity to earn up to 82 total points in this course. Up to 70 points can be earned from homework assignments (5 in total)—these will be graded for accuracy. Up to 12 points may be earned from submitting outsideofclass formative assessments (6 in total); these will be graded on effort only—incorrect answers will not be penalized. Extra credit opportunities have not been changed.
In order to provide participants with prompt feedback, late homework assignments will incur a 3point penalty. However, extensions will be granted as needed for extenuating circumstances (e.g., conferences, comprehensive exams, family obligations) if requested at least two weeks in advance of the due date. Late or incomplete outsideofclass quizzes will incur a 1point penalty when submitted. A final grade of “incomplete” will only be given in dire circumstances and entirely at the instructor's discretion.
REVISION for Weeks 1116: Given the general chaos of our world right now, the penalty for late assignments will be removed effective 3/30/20, but participants are still encouraged to complete homework and formative assessments by the recommended due dates. However, the hard deadline for the end of the semester must remain intact: all outstanding work must be submitted by Friday, May 15, 2020 at 11:59 PM.

As a reminder, the University of Iowa College of Education has a formal policy on academic misconduct, which all students in this course are expected to follow. Please consult the instructor if you have questions.
Students with disabilities or who have other special needs are encouraged to contact the instructor for a confidential discussion of their individual needs for academic accommodation.
It is the instructor's intent that students from ALL backgrounds and perspectives feel welcome and encouraged to participate in this course. There is no such thing as a “stupid” question or answer. All course participants—enrolled students and auditing visitors—should always feel welcome to ask whatever questions will be helpful in helping them understand and follow the course content. You may do so during class, in office hours, over email, or in individual appointments with the instructor (available by request).
The instructor realizes that this course is not your only obligation in your work or your life. If work or life events (expected or unexpected) may compromise your ability to succeed in this course, PLEASE contact the instructor for a confidential discussion (in person or over email, as you prefer) so that we can work together to make a plan for your success. Please do not wait to do so until you are too far behind to catch up!
Participants will also need to have access to software that can estimate the models presented. Although the course will feature SAS and STATA primarily, other software packages (e.g., SPSS, R) can also be used to complete homework assignments. These packages are freely available to University of Iowa members through the UIowa Virtual Desktop but STATA is not available offcampus. Another option that allows the use of both SAS and Stata offcampus is the Research Remote Desktop. See info here: https://its.uiowa.edu/rrds.
