does autocorrelation introduce bias what is the definition of fixed effects in math what is the relationship between auto-correlation and bias what type of auto correlation introduces bias why should a fixed effects estimator be based on a dependent variable does autocorrelation introduce bias what does a fixed effects estimator do? what is the effect of autocorrelation does autocorrelation introduce bias why do fixed effects models introduce bias when a variable is auto correlation do autocorrelations introduce bias what is the importance of a fixed effects estimator when independent variables are correlated with dependent variables, bias can be introduced into the estimator. what variables are in a fixed effects estimator when a dependent variable is correlated with an independent variable, bias would be introduced into the model as the result of auto-correlation. how are bias and auto correlated variables related? why do fixed effects models use autocorrelation what is the difference between a fixed effects model and autocorrelation? do autocorrelation variables introduce bias in a fixed effects model?
