lm_gradient: Fitting Linear Models with gradient

In vincnardelli/gradient: Gradient

Description

lm_gradient is used to fit linear model with gradient or steepest descent.

Usage

lm_gradient(
  b,
  formula,
  data = NULL,
  maxit = 1000,
  tolerance = 1e-05,
  stepsize = 1e-04,
  fun = "sd"
)

Arguments

b	initial values for beta
formula	an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted
data	an optional data frame, list or environment. If not found in data, the variables are taken from environment(formula)
maxit	number of max iterations of the algorithm
tolerance	the algorithm will stop if tolerance is reached
stepsize	size of each step (only for gradient descent)
fun	function can be sd for steepest descent or gd for gradient descent

Value

the function returns an object of class "gradient"
