Hello!
I am trying to perform an ordinal logistic regression (or at least I think I am) and I'm a bit stuck.
My variables are all categorical or ordinal:
DV: High, Medium, Low
IV: Parent Gender: 0,1
Child Gender: 0,1
Essentially, I am trying to understand if a parent's gender...
Hello,
I need help determining what analysis to run. I have 2 independent variables (a control and experimental condition) with 4 dependent variables (one scale with 4 subscales, each of which I assume should be treated as a dependent variable.)
This is Likert data (ordinal) so I thought I...
Hello and thanks in advance for any response...
I have 60 likert-type questions (5 items) (and their responses of course...) and age. Age as raw data is continuous. On a duplicate file I have categorized age in 5 age groups (ordinal) as I want to test whether age can affect the adoption of...
Hi,
I seem to have gotten a little confused about the possibility of comparing groups in ordinal logistic regression.
Here is my issue:
I gave people one of three framing conditions for the goal of a task, which varied in the wording of how the goal was presented. Then I let people perform...
Hi all,
want to do an ordered logit regression. I have data from different sources and need to use the source as a selection variable for the dependent variable (only for the dependent variable, not for the regressors!).
I know how to do this for a linear regression. Is there a way to do this...
I have designed a question and now intend to use SPSS to run regression to analyse the results:
My dependent variable is: intention to vote. Yes or No.
My independent variables are: a series of question ranked on a scale from strongly disagree to strongly agree.
I want to test whether the...
Hi All,
I am looking at data showing injury to intervertebral discs. Injuries are graded on a 4 point scale with 0 being no damage and 3 being maximum damage. What we seeing is that when there is an injury at one disc, there seems to be an injury in the proximal disc.
What we are trying to...
I am using ordinal regression (MASS package, polr command) to analyze ranked coloration data (% piebaldism) of an iguana species based on sex, snout-vent length (SVL), and location. I'm concerned that skewed SVL between the locations (some locations have a large average SVL and others have small...
First of all, I am a complete newbie to stats from a non mathematical background, but I need to analyse survey data for my dissertation!
So I have a dependent variable that is ordinal - it's a 5-point likert item (strongly disagree - strongly agree). My independent variables are composite...
Hi!
This is a really simple question, but one for which the answer continues to elude me!
I understand that in a binary logit regression the resulting logit is the probability of an event occurring, defined as
Ln(P/1-P)
However, in an ordinal logit, in which there are multiple...
Hello,
I'm working with a dataset and should do univariate regression on it, to see if there are a relationship between the response variable, nominal with three categories, and the explanatory variable, values between 0-5 (would say it is nominal).
I would like to get a result where you can...
Hi All,
I'm analyzing survey results with many responses coming in the form of Likert scales. In this case, I actually have two Likert scale predictors (in the model as nominal variables) predicting my ordinal dependent variable. My two predictors each have five categories (levels on the...
Hello everyone,
I have a problem with the graphical output of a ROC curve I am calculating.
I am sure it is very silly but I cannot figure out where I am going wrong.
I estimate the probability of damage (damage levels 1 to 5) to a number of buildings given one continuous explanatory...
Hello everyone,
I need to conduct a mediation analysis in which all the variables (i.e., the predictor, mediator, and outcome) are single items measured on 4-point Likert type scales (i.e., strongly disagree, disagree, agree, strongly agree). I have conducted ordinal (probit) regression...
I am running a ordinal regression model with spss plum. I would like SPSS to print me the intercept, but somehow I can't find the synax command for it. Anyone familiar with the problem?
Thanks in advance!
What is the correct method for deriving a formula from the results of an Ordinal Regression, that can be used to predict the value of the dependent variable for new cases?
Thanks very much in advance to all for any info.
Best,

I am having problems with doing an ordinal regression analysis that I hope you can help me with.
I have one ordinal variable (dependent) and want to analyse whether three other ordinal variables (independent) may explain the dependent. All variables have three levels. To do the analysis, I...
