interpretation

I try to improve my statistical knowledge and right now I am working on a regression that contains interaction terms. I am currently investigating the effects of different variables (a1, a2 etc.) on the quantity of chairs sold in a transaction (dependent variable). To see if effects are...

Hello, I’m needing a little bit of direction in understand my first hierarchical multiple regression data. My research question is to what extent does alcohol explain the association between negative mood and impulsivity in academic performance (DV). I’ve ran the analysis - at the first stage...

Hello, I have categorical data (high/low) on a protein which I am investigating its potential role as a prognostic utility. I have run a cox regression with the categorical data and 3 year survival as outcome (dead/alive) I get a significant results (attached). I then ran...

I am working with a structural VAR analysis, and want to understand my results. The model studies how a shock on one variable affects a second variable. I understand that if the first month's response is +3 %, it means that the initial value of the response variable increases by 3 percent...

Hello everyone, I would really appreciate some advice on how to interpret my SPSS-Output. I have tried to figure it out myself, but haven't been able to get an answer. I have 2 binary independent variables and 1 dependent variable with 3 categorical outcomes. So a 2x2 Design. In order to...

I am running a logistic regression to find how font manipulation (x1) and people perceptions over how easy it is to process the information (x2) influence the online buying behaviour (y). I was especially interest to see if x2 acts like a moderator. Initially I have got to the following...

So effectively I have two variables, language problems, and emotional problems, both of which independently cause an increase in a third variable, which is behaviour problems. I hypothesized that high emotional problems would significantly moderate the relationship between language problems and...

I have carried out a Moran's I test on the residuals of a GLM model in the "ape" package in R which has returned the output below: Observed: -0.158 Expected: -0.0303 SD: 0.058844 Probability: 0.030002 On this basis is it correct to state that there is negative spatial autocorrelation...

This study tried to determine the factors influencing the probability that voters would be asked to show ID in order to vote in a certain state during a certain election. (Model 1 identified Hispanics by self-identification and Model 2 identified Hispanics by whether they had an Hispanic...

Hello evetyone! I conducted factor analysis on a 30-item scale which is suppose to be measuring xenophobia. All the variables were previously recoded in order to express the same side of the measured dimension. (I am using SPSS) I intend to analyse the relationship between xenophobia and a...

Hello everyone, I am a newby to that forum, so I hope my question is not redundant. I am currently sitting on my master thesis where I investigate which effect diversity in teams has on publications. Herefore, I have a dependent variable 'publications' which is a count variable. I have two...

Hey everyone. This is my first post here so please be kind to me :) . For my thesis my aim is to run a moderation analysis between organizational commitment and training. My dependent variable is job satisfaction. Org.commitment comes from 4 5-point likert-items, therefore I calculated the...

Hi, I am using the glmer() function from the package lme4 for a mixed logistic regression model. Here, the formula is Y ~ X + Z + X:Z, where Y is the binomial outcome, X is a categorical predictor with 3 levels (X1, X2, X3, where X1 is the baseline), and Z is a continuous predictor. In the...

Hello, I am analyzing an experiment in which we tested the effect of different treatments on trauma. So, for example, blood pressure (and other parameters) is followed in animals exposed to trauma and treated in different ways. I am using the Proc mixed procedure to analyze my data with...

Hello everyone, I tried to do cluster analysis for my class, but I'm not sure how to interpret the plot I got. Can anyone help me with that please? Thanks, Tomer.

Hi there, I am running a Multiple Linear Regression analysis. I have 2 predictor variables (self-worth and self-acceptance) and 1 criterion variable (self-esteem). As hypothesized, self-worth and self-acceptance reliably predicted the scores on self-esteem (eg. higher scores on the...

Hi all, I have run a factor analysis to test reliability and validity of an established scale and found simple structure with my own sample, which is great. I found a difference between the factors that explain most of the variance in the established study and my study. Now I am discussing...

Hi, I am learning TS analysis but my angle is probably diffent from the usual. Being in six sigma I need to reduce the variability of a process that I can prove is basically AR(3) which with 3 runs on the average per day means one day's runs influence the next day in the mathematical model...

hi, looking at process times of a rather complex machine I found that an AR(2) model describes it quite well. Does it make sense to interpret this as an indication that the machine has a "memory" of about 2 runs ? E.g. insufficient cleaning between runs? thanks a lot!

Hi everyone... Please help me with the following question I'm doing my research that one of it aims is to test the model fit of a particular model. I'm having a problem to draw the conclusion of the fit of the model since it has various model fit indices that show different result. Below is...
