variable is measured with error they say it just affects the standard errors but this doesn't make much sense to me because we are estimating the effect of $X$ not on the original variable $Y$ but on some other $Y$ plus an error. So how does this not affect the estimates? In this case can I also use instrumental variables to remove this problem? regression econometrics instrumental-variables share|improve this question edited Dec 22 '14 at 10:38 Andy 11.8k114671 asked Dec 22 '14 at 10:10 TomCat 3314 add a comment| 1 Answer 1 active oldest votes up vote 9 down vote accepted When you want to estimate a simple model like $$Y_i = \alpha + \beta X_i + \epsilon_i$$ and instead of the true $Y_i$ you only observe it with some error $\widetilde{Y}_i = Y_i + \nu_i$ which is such that it is uncorrelated with $X$ and $\epsilon$, if you regress $$\widetilde{Y}_i = \alpha + \beta X_i + \epsilon_i$$ your estimated $\beta$ is \begin{align} \widehat{\beta} &= \frac{Cov(\widetilde{Y}_i,X_i)}{Var(X_i)} \newline &= \frac{Cov(Y_i + \nu_i,X_i)}{Var(X_i)} \newline &= \frac{Cov(\alpha + \beta X_i + \epsilon_i + \nu_i,X_i)}{Var(X_i)} \newline &= \frac{Cov(\alpha ,X_i)}{Var(X_i)} + \beta\frac{Cov(X_i,X_i)}{Var(X_i)} + \frac{ measure its prediction error is of key importance. Often, however, techniques of measuring error are used that give grossly misleading results. This can lead to the phenomenon of over-fitting where a model may fit the training data very well, but attenuation bias proof will do a poor job of predicting results for new data not used berkson error in model training. Here is an overview of methods to accurately measure model prediction error. Measuring Error When building prediction models, ## Modeling Error Definition the primary goal should be to make a model that most accurately predicts the desired target value for new data. The measure of model error that is used should be one that achieves this goal. http://stats.stackexchange.com/questions/129991/why-doesnt-measurement-error-in-the-dependent-variable-bias-the-results In practice, however, many modelers instead report a measure of model error that is based not on the error for new data but instead on the error the very same data that was used to train the model. The use of this incorrect error measure can lead to the selection of an inferior and inaccurate model. Naturally, any model is highly optimized for the data it was trained on. The http://scott.fortmann-roe.com/docs/MeasuringError.html expected error the model exhibits on new data will always be higher than that it exhibits on the training data. As example, we could go out and sample 100 people and create a regression model to predict an individual's happiness based on their wealth. We can record the squared error for how well our model does on this training set of a hundred people. If we then sampled a different 100 people from the population and applied our model to this new group of people, the squared error will almost always be higher in this second case. It is helpful to illustrate this fact with an equation. We can develop a relationship between how well a model predicts on new data (its true prediction error and the thing we really care about) and how well it predicts on the training data (which is what many modelers in fact measure). True\ Prediction\ Error = Training\ Error + Training\ Optimism  Here, Training Optimism is basically a measure of how much worse our model does on new data compared to the training data. The more optimistic we are, the better our training error will be compared to what the true error is and the worse our training erro
