The studied pharmaceuticals included antibiotics, analgesics and anti-inflammatories, cholesterol …It is shown that the model that is selected by the lasso can be extremely sensitive to the fold assignment used for cross-validation. A consequence of this sensitivity is that the results from a lasso analysis can lack interpretability. To overcome this model-selection instability of the lasso, a method called the percentile-lasso is introduced.Aug 1, 2008 · Abstract. Group lasso is a natural extension of lasso and selects variables in a grouped manner. However, group lasso suffers from estimation inefficiency and selection inconsistency. To remedy these problems, we propose the adaptive group lasso method.

Electricity price forecasting (EPF) is nowadays perceived as fundamental for decision making in energy markets. As short-term transactions provide a tool for adjusting long-term positions and a benchmark in over-the-counter trading, the day-ahead, intraday, and balancing prices play a key role in day-to-day operations (Kath and …The Lasso highlights the presence of several peaks which are roughly centered at the same location of peaks obtained via the ridge regression. In the Lasso results, a stronger oscillation of the solution in terms of its average value as well as of the 3σ bounds is also present. This behavior is due to the complex nature of the Li-ion battery ...The hybrid methodology adopts the adaptive LASSO regularization to simultaneously reduce predictor dimension and obtain quantile forecasts. Several recent empirical studies have considered a large set of macroeconomic predictors and technical indicators with the goal of forecasting the S&P 500 equity risk premium.The Lasso is a popular model selection and estimation procedure for linear models that enjoys nice theoretical properties.

In addition, results from adaptive LASSO and GAM suggested a super-additive interaction between molybdenum and selenium (both p-values = 0.04).Despite the clear success of forecast combination in many economic environments, several important issues remain incompletely resolved. The issues relate to the selection of the set of forecasts to combine, and whether some form of additional regularization (e.g., shrinkage) is desirable. Lasso peptides are a structurally unique class of bioactive peptide

Abstract. A new estimator, named S-LASSO, is proposed for the coefficient function of the Function-on-Function linear regression model. The S-LASSO estimator is shown to be able to increase the interpretability of the model, by better locating regions where the coefficient function is zero, and to smoothly estimate non-zero values of the …START NOW 100 6 Theory for the Lasso so-called margin condition, which is the behavior of the theoretical risk near its minimizer. Section 6.5 provides a benchmark for how good empirical risk minimizers behave if one knows the relevant variables. Section 6.6 gives conditions for consistencyAgainst this background, and also considering the frequently-found good performance of simple-average combinations, we propose a LASSO-based procedure that sets some combining weights to zero and shrinks the survivors toward equality (“partially-egalitarian LASSO”).Nov 17, 2016 · Subset selection.
