    How to deal with observations error in linear regression

    I have data of 11 predictors and 1 response with 1000 observations and i'm doing linear regression on the data. I also have the measurements errors for the predictors (not for the response) and i'm struggling in find out hoe to count for them in the total error estimate, because basic multiple...

    Dear all, Given a sample of N points extracted from a distribution, I would like to know how to estimate the error on the higher moments of the distribution, such as the standard deviation, the skewness and kurtosis. In other words, I know the error on the mean is simply sigma/sqrt(n), but...

    Estimation of the position accuracy of 2 set of points with different cardinalities

    Hi everyone, A simple question: I have 1 set of 2D location points A that I use as reference. I have another set of location points B generated by observations. Is there any standard method/measure to estimate a kind of position accuracy error knowing that - A and B dont have the same...
