Lasso penalized linear regression with different optimizers
lasso(y, ...)
y |
A list object of one of the four classes: 'cv', 'stability', 'multiSplit', and 'simultaneous'. If x is NULL then y should a list of two components y and x, y is a vector of expression and x is a matrix containing copy number variables |
... |
other parameters |
The function contains various optimization methods for Lasso inference, such as cross-validation, randomised lasso, simultaneous lasso etc. It is specifically designed for multicollinear predictor variables.
Varied depending on the optimizer used. Generally it contains
beta |
coefficients |
residuals |
residuals of regression model |
fit |
the corresponding fit of regression |
