x	input numeric vector
param	parameters needed for the function, takes the form of numeric vector. Unused for L1 and L2.
derivative	logical, whether the return is the loss value or the derivative.

Value

Loss(or derivative) value at x.

Examples

RSAVS_L2(1 : 10)
RSAVS_L1(1 : 10)
RSAVS_Huber(seq(from = -3, to = 3, by = 0.1), param = 1.345)
RSAVS_Huber(seq(from = -3, to = 3, by = 0.1), param = 1.345, derivative = TRUE)
