    Dummy variables in fixed effects models

    I am doing a research on factors influencing firm performance, So I am fitting a fixed-effect modelling approach in R using 3-year panel data, with a total of 193 firms, these firms are grouped into 4 different sizes (Medium, Small, Very Small and Micro depending on thier annual sales levels). I...

    CI to percentage change in ICC

    I'm running fixed effects models to estimate changes in intra class correlations. I first run an unconditional model and then a second model including only level-2 factors. I'm interested in the reduction of the icc when adding only level-2 factors. I'm interested in expressing the...

    Distribution of fixed effects

    Hi all, Let me shortly introduce my research: I am looking at whether companies outperform each other in investments. To do this I observe them at multiple investments, and calculate fixed effects. Afterwards, I tested the fixed effects to confirm whether at least one company outperforms...

    Split file regression, or Fixed effects Mixed model

    Within a dataset that has a few variables explaining dependent variable A, and influences vary over different categories, it can be obvious to split the file in these categories and run a regression. However, there is also the possibility of running mixed models with fixed factors. What would...

    General linear model or mixed linear model

    I am doing my thesis for my master degree. I am looking at determinants of profitability for commercial banks. Overall, I have Return on Asset as a dependent variable. As independent variables I have chosen Leverage, credit risk, liquidity risk, size effect, gdp, inflation, interest rate...

    Interaction effects in Fixed Effect Models

    Dear all, I am currently writing my Master thesis and in addition to finding a relationship, I examine whether the relationship between X and Y became stronger over time. I use a firm fixed effect model, and this is my base regression: (1) CFO_TURNOVER = α0+α1INDUSTRY SHOCK+ ΣCONTROL...
