regression analysis

In an experimental study, the aesthetic value (independent var) of a picture is manipulated into (low and high quality). "Low Quality" -- to make it look less appealing; and "High Quality" to make it look "very attractive." I want to examine the effect of "Low" and "High" Quality images on the...

hi , i have two questions: 1)- is it adequate to run a multinomial logistic regression test using spss on two categorical variables to test the influence relationship, knowing that data is collected via likert scale items and then computed into 5 classes : example from 5 to 10: weak, from 15...

Hi, I want to examine the effect of still images (independent var) with two levels (monochromatic and multi-color) on mood perception (dependent var) of participants. What is the appropriate analysis I must conduct in this case? Furthermore, I conduct a regression analysis to examine the...

Hello all hope this is the right thread for the question and that someone will be able to help me out :confused: I have created a propensity matched control for my case group and am unsure now which test to use for statistical comparision of my outcome variables (most categorical, some...

Hi, 1.I am planning to examine the level of user engagement of participants playing a particular computer game, that has two versions, one in color and the other one in black and white. I understand that I can conduct a one way-within subject test ANOVA to compare the means of the two groups...

Hi, I have data from two very different sources (bird counts from ships and bird counts from the shore) which aim to estimate the same population/outcome. Both data have different covariates/predictors and thus it is difficult to combine both data in the same regression model. Does...

I am doing a program evaluation and want to use difference in difference analysis. I calculated the difference in difference by hand and now want to perform a regression. I have made a dummy for 1=treatment and 0=no treatment. But since I have done my pre and post test on the same...

Hello, I am currently doing a thesis which aims to explain returns of stocks in function of the ownerships of some stakeholders. In the Excel attached, I would like to explain the returns in the last column with the two explicative variables ( Venture Capital % Ownership and Hedge Funds %...

Hello, It would be great if somebody can help me with this: Is it correct to conduct factor analysis on data source (A) and then run a simple regression analysis with derived factor from factor analysis as independent variable and a item from the same data source (A) as dependent variable...

Hi, I am looking for all possible sources (literature, articles, books) with descriptions how to transform different kinds of regression analysis outputs in event probabilities (if feasible). Any help is wellcome. Thanks!

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...

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...

Hi, I want to model a bird population in a country via regression analysis (Poisson regression due to count data). In order to optimize the sampling effort versus precision, I use a stratified random design: The country is splitted into 10 different habitats, and from each habitat I draw...

Dear all, I have 3 fitted lines: Y = b0 + (b1)X Y = (0.5)b0 + (b1)X Y = b0 + 0.5(b1)X Where and In addition to the the 3 equations above, using the information provided by the image attached I would like to determine (theoretically), which one of the three fitted lines (listed...

Hi, I am experiencing difficulties in understanding the following question; I have been assigned two variables (X and Y), and have been given a data-set which consists of 50 data entries for both variables X and Y, ranging from 15-60. I have also calculated ƩX, ƩX^2, ƩXY and ƩY. Essentially...

Hi! I will be using a gravity model for my master thesis (not an economics/statistics major) focusing on remittance flows within the EU. I am familiar with the gravity model but have a fairly basic question to which I have not found the answer through books or articles.. or at least I have...

Hi, I have a set of 25 points and I used a TI-84 calculator to calculate the linear, quadratic, logistic, exponential, and power regression models for this data set. I have, likewise, obtained the r^2 value for each of these regressions. Some of these r^2 values appear to be quite similar. For...

Hello everyone! I’ve been pondering this question for some time. I’ve searched online and on this forum and I haven’t found the answer to my question. Throughout my searches online I’ve found that Shapley values are obtained by running all the possible combinations of predictors against the...

Hi Stats Gurus, This question is about a regression analysis that I want to run, but I am not too familiar with this type of analysis. I have conducted MANOVAs to isolate variables that are significant out of the ones that were theoretically relevant for my analysis. I would now like to...

I ran a survey across all 50 states in the US. The goal is to see if there is a correlation between people's love for the state and the population growth % over 5 years. The survey has 15 questions - all on Likert scale (1 to 5 Strongly Disgaree to Strongly Agree) - questions about people's...
