Connect and share knowledge within a ecological meaning in tamil language location that is dxample and easy regressiom search. I'd like to simulate data for a multiple linear regression with four predictors where I am free to specify. I arrived at a solution that fulfills the first two points but is based on the assumption that all independent variables are not related to each other see code below.

The code above first samples the predictor variables with a given degree of correlation among each other. Then a column for the error is added based on the desired value of r2. Then with all of that together a column for y is added. But if x-variables are related, every beta is not! That means the variance of the error has to be bigger, because the variables exwmple some variability from each other.

In the case of the interrelation being 0. Assuming that all interrelations are equallike this, any degree of interrelation among the independent variables can be specified, together with the true standardized regression coefficients and an desired R2. Lion Beherns's answer starts in the right direction but it is mathematically wrong, and it is also less general than it could be. None of the existing answers get this right. Instead, they assume the simple linear regression example in r of the predictors equals 1 and sum their squares and then simple linear regression example in r the correlations not the covariance.
