Deming regression. Still not very popular.

Deming regression - IxStat We all know the common OLS regression linear models. In this kind of models we assume that Y depends linearly on some let us assume continous predictor X plus and we account for the measurment error for Y as: Y_i=A+B*X_i, i is the index of the i-th observation on X and Y. Note that from this regress...

Interactions and why we all get them wrong? - IxStat Where the interpretation of the interaction comes from? Let us assume that we have patients in out sample and a linear model (simple or mixed). For the linear model we have an equation of the form: Y=A0+A1*X1+A2*X2+A3*X1*X2, where A0 is the intercept and A1 and A2 are the main effects of X1 and X2 r...
