Good day everybody, The following problem. I wanted to calculate a multiple regression in SPSS, my dependent variable is grief, my independent variable is the bond and the animal species. I have since recoded the animal species into dummy variables. The problem now is, if I calculate an independent variable, for example the animal species…
Hello everyone, For my thesis, I have to conduct several moderation analyses. Unfortunately, I had 10 different questionnaires with different Likert scales and dichotomous Rush scales. I z-standardized all Likert and dichotomous items. Now I plan to create variables with means and run moderated regressions using Hays' Process for SPSS. Has my approach been correct…
Hello, does anyone here know anything about SPSS? I've already prepared my data and wanted to perform a linear regression. I calculated the means. My problem is that the requirements of linear regression are not met and only partially by transforming one variable. Can someone please give me some advice on what I should do…
What is the difference between statistical methods vs. machine learning? What do linear regression, GLMs and ARIMA belong to one/both?
I think I was always like that and then when I was 16 or 15 I had a word for it.
I want to perform a multiple regression in SPSS. The tables and data look fine. However, this scatter plot is coming out. What am I doing wrong? Or is it possible that such a diagram exists? If so, how do I interpret it?
Dear all, As part of my bachelor thesis I ask: How do I interpret the regression if Corrected R^2 = .482 ANOVA significant with .014 But: All but one coefficient are not significant (already tested for multicollinearity, tolerance and VIF value are OK) This is a rare disease, and the sample includes 50 patients. The…
Hi everyone, I have a quick question. I would like to conduct a regression analysis with an interaction term. However, there are a few prerequisites for this that are a bit confusing for me. I'll leave out the two prerequisites that the variables must be metrically scaled and normally distributed (they already apply). Now I…
Hello, I seem to have forgotten the unit in the function equation and the documentation is missing. Can someone please tell me which unit should go there? And how I should have done the documentation. Task 1.
I am currently writing a paper on anorexia nervosa (anorexia nervosa) and would like to investigate to what extent successful therapy limits the occurrence of concomitant illnesses (depression, anxiety disorder, obsessive-compulsive disorder, etc.). What statistical test is best for this? I was thinking of an ANOVA, but then both variables would be nominal/ordinal scaled. Would…
If you want to perform a linear classification and you have 10 attributes, some of which are binary (0 or 1) and some of which are continuous (such as income 2000 – 6000), how do you find out whether you should normalize the values and on which of the two scales?
