regression analysis

Hello community :) I am currently working with paneldata to see if there is correlation between sustainability and performancce in the energy and materials sector of the S&P500. I ran the regression twice, one with the logarithm of MarketValue (=MarketValue.WINS.LOG) and one without...

What's the statistical difference between simulating the dependent variable and simulating the error terms and adding them to the fitted values values assuming normality (gaussian GLM)? Say I'm doing a simple multiple regression on the following data (R): n <- 40 x1 <- rnorm(n, mean=3, sd=1)...

How to find adjusted OR as given in Table 6 in spss? The procedure followed to get it like i found binary logistic regression is used to find crude OR using single indep. variable.

Hi all I'm fairly new to statistics and have a project where I investigate if the difference between two variables can predict the value of a third variable. And I am unsure if I should use simple or multiple regression. The participants in my sample has answered three surveys: A) Emotions...

I have a study to establish the factors that influence consumer satisfaction with different internet banking services. Part 1 is the demographic and Part 2 are the Customer Satisfaction and Attributes of Satisfaction which were measured using the 5 Point Likert Scale questionnaires. The...

I have data collected with 5 Likert Scale Questionnaire to establish factors influencing customer satisfaction using online banking. The factors included Credibility, Efficiency, Ease of Use, Security, Problem Handling and Product/Service Portfolio. A total of 6 independent variables. In this...

Hi! I am using three surveys, let's call them A, B, and C. From one survey to the next, there is a 5-year interval. From these surveys, I calculate the weight change and I then check if they get a certain diagnosis afterward within 10 years. I want to see if weight increase or decrease is...

I am evaluating whether utility-scale solar energy plants affect the surrounding climate (initially temperature). An effect has been found in one paper using the approach described below/attached but when repeating this approach I find no effect for the same site. I want to be sure that there...

I was using a fixed-effects panel model with interaction effects when I realized that the VIF values are too high for some variables. I was advised to standardize the predictor variables to mitigate multi-collinearity. My question is that can I standardize just 1 predictor variable or must I...

Dear members, Just a newbie to statistics. Request your help with understanding this table below I have serious doubt in the results of statistics that I have done with regard to the odds ratio and p value that I obtained. My question is that how come that when the OR is low the p value is...

Hi, everyone, Based on the forecast turnover, I am supposed to predict various activities (such as the number of manually entered orders, number of phone calls etc. (17 activities in total) in a company.My first thought was to do a linear regression per activity to be predicted. Means to...

Hi, I'm just wondering if anyone here can help me. I'm making a model for my logistic regression. For the variables, I'm using 1 Dichotomous Dependent Variable (Financial Distresss, Y) and 2 Continuous Independent Variable (Corporate Governance Score, X and VAIC Score, Z). I'm using logistic...

Hello all, I have a problem for a university assignment that two dummy variables are mutually exclusive. The task is to estimate what can increase certain diseases in dogs using regression. In the sample there are several factors (Lives in city yes/no, age, male/female etc....). Then there is a...

I have a question about multiple regression. May I kindly ask how should I interpret the conditional main effect when the interaction is 0 and the coefficients have opposite signs, more specifically if one of the interaction term contains zero such as angle or time. Please see an example...

Hello, I am doing a longitudinal multilevel analyses. I am researching the impact of certain restricting abortion policies of US states on the number of abortions. Furthermore I control for the characteristics of these states. One of these characteristics namely poverty rate of a state, has a...

Hello, I'm hoping someone can help me. I am conducting research for my thesis looking at relationship between social connectedness (IV), and diabetes distress, diabetes self-management and perceived competence (DVs). All are continuous variables measured on self-report likert scale...

I'll start off saying that stats in general has never been a strong point for me :D The variables i am using are; Gender Age Relationship Status Number of dependants Profession Neuroticism (Higher score = higher neuroticism) Affectivity (Higher score = positive; lower...

I'm currently analysing two sets of time series data (monthly temperature and forest cover over a 10 year period). I first ran a Mann Kendall on each variable (they're non-normal) after removing seasonality, and found that they both show a significant increasing trend - vegetation faster than...

Hi guys! I am gonna model multiple linear regression. Do you think that normality of residuals assumption is met according to the P-P plot? Also, consider the homoscadasticity assumption according to the scatter please. I am writing my Bsc. thesis, what should I do if these two assumptions...

Hello everyone, for a multiple regression I am currently trying to understand if there is sufficient linearity between my predictor and response variables to see whether I can carry on with a regular linear regression. I have three models, with one dependent and the same three...
