compare coefficients

    Test for comparing correlation values. The winner is?

    Hi everyone, my problem is relatively simple, but trivial. I've already read some topics about that, but I really need straightforward answers and/or opinions. I have data divided by one fixed effect (Emotion, with 2 levels: negative and neutral), and I have a covariate (reaction time) for...

    Linear regression or multivariate regression?

    Hi there, I am pretty much a newbie in statistics and I hope you can help. I have an experimental design where I analyze three time-windows before the stimulus onset and three windows after. I have three conditions under which the brain responses are obtained. I want to see to what extent...

    How can I compare regression coefficients in a same multivariate regression mode

    Hi, I think this question has been answered in bits and pieces here and there, but I am still a bit unsure about what the best approach for this is: how to compare two coefficients from a regression to see if the effect strengths are significantly different. For ex, I am interested in...

    Compare coefficients across Cox regressions to conclude x1 is more harmful than x2?

    Hi, Our question is regarding to comparison of effects of different variables in survival analysis. Usually, the Cox model tests the effects between different levels of a variable e.g. between treatment and placebo, but would it also address the effects between variables? We keep...

    Need help with comparing regression coefficients between different models

    Hello, I am estimating two multinomial logistic regression models, each with the same dependent variable, but with different main independent variables. Is there a way to determine (perhaps I need to do this by hand) whether the coefficient in my main IV in Model 1 is statistically...
