    Averaging LASSO coefficients for repeated random partitioning of data

    Is it reasonable to average LASSO coefficients from repeated reshuffling of training/test sets? Suppose I randomly divide my data into testing & training sets, then within the training set use 10-fold cross-validation to choose an optimal λ, then refit on full training data and record the...
