Hi, I am currently working on a paper where I run a VECM and get significant values. However, I am not quite sure about how to interpret the output and how take the different values and express them with an equation. I run the test in SATA using the vec command Attached is a picture of...

Hi - I need to control for two variables in my linear regression, the code thus far is; sort dde2 by dde2: regress sustain I have two mediator variables or control variables, gender and ses and I need to remove their effects. Any help greatly appreciated!

this question asks for help for a statistical/econometric problem I can't get the clue: I have a classic multivariate regression problem, i.e. dependent variables are stored in matrix Y having dimension n x p. So p observations come from the same respondent i and we need to expect correlated...

Hello, I am quite familiar with mixed effects (multilevel models) in meta analyses. Now, I want to do a mixed effects (multilevel) meta analysis structural equation model (MASEM) with STATA and the gsem package because my data format is long. My data look like: `id studyId...

Does anyone know how to test the hypothesis that the difference between people without and with kids = -1 per night in Stata? I have the data set with kids as a dummy variable, but can't figure out where to start.

Hi I am currently writing an assignment regarding a trade model using a gravity equation. The dependent variable in the model is Ln(X) and the non-dependent is both Ln (GDP, distance and so on) AND binary variables. So the question is: can I use SPSS for this kind of modelling or would...

I'm sorry if this is a total noob question, but I cannot figure it out. When I'm adding variables into my regression into STATA, the degrees of freedom (and observations) decreases significantly. In particular, adding one variable decreases them by about 1,000. I am only looking at the same 6...

Dear All, I have a small question I hope you could help me with. I am trying to find a predictive model for a dataset doing a stepwise logit regression. I have a few variables with info that is included in another variable. E.g. "income" (0-9 with 0=income is missing) and "income...
