Description Usage Arguments Value
This function implements an orthogonal projection version of the L2Boosting algorithm.
1 | L2BoostOGA(X, y, iter = 200)
|
X |
matrix of regressors |
y |
dependent variable |
iter |
number of iterations |
The functions returns an object of class L2Boost
with the following components:
BetaFinalthe estimated final parameter vector.
BetaFinal0the estimated final parameter vector of the orthogonal boosting algorithm.
BetaVectorvector where each component gives the values of the estimated coefficient in each round.
Resmatrix with the estimated function values in each round
Res_betamatrix with the estimated coefficient vectors from each round
iIteration when the process was terminated.
Svector of the indices of the selected variables in each round
sigma2estimation of the variance
stop_ruleWhen the stopping rule, stopped the algorithm.
itermaximal number of iterations of the algorithm
ymodel response / dependent variable
