compare coefficients

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...

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...

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...

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...

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...
