Description

Create distributed lag terms

Usage

distributed_lag_list(
  x,
  n_lag,
  lag_max,
  df,
  degree,
  internal_knots,
  boundary_knots,
  complete_basis,
  periodic,
  derivs,
  integral
)

Arguments

`x`	numeric vector to lag
`n_lag`	number of lag terms
`lag_max`	integer the maximum lag
`df`	Degree of freedom that equals to the column number of the returned matrix. One can specify `df` rather than `knots`, then the function chooses `df - degree - as.integer(intercept)` internal knots at suitable quantiles of `x` ignoring missing values and those `x` outside of the boundary. For periodic splines, `df - as.integer(intercept)` internal knots will be chosen at suitable quantiles of `x` relative to the beginning of the cyclic intervals they belong to (see Examples) and the number of internal knots must be greater or equal to the specified `degree - 1`. If internal knots are specified via `knots`, the specified `df` will be ignored.
`degree`	A nonnegative integer specifying the degree of the piecewise polynomial. The default value is `3` for cubic splines. Zero degree is allowed for piecewise constant basis functions.
`internal_knots`	location of internal knots
`boundary_knots`	location of boundary knots
`complete_basis`	logical intercept?
`periodic`	A logical value. If `TRUE`, the periodic splines will be returned. The default value is `FALSE`.
`derivs`	A nonnegative integer specifying the order of derivatives of splines basis function. The default value is `0`.
`integral`	A logical value. If `TRUE`, the corresponding integrals of spline basis functions will be returned. The default value is `FALSE`. For periodic splines, the integral of each basis is integrated from the left boundary knot.
