R: Generating Integrals of Basis Terms

mkint {gss} | R Documentation

## Generating Integrals of Basis Terms

### Description

Generate integrals of basis terms for use in the ssden1 suite.

### Usage

    mkint(mf, type, id.basis, quad, term, rho, rho.int)
    mkint2(mf, type, id.basis, quad, term)

### Arguments

`mf` | Model frame of the model formula.
`type` | List specifying the type of spline for each variable.
`id.basis` | Index of observations to be used as "knots."
`quad` | Quadratures on marginal domains, weighted by rho.
`term` | Model terms generated by `mkterm`.
`rho` | Marginal log(rho) on quadrature points.
`rho.int` | Marginal integrals of log(rho).

### Details

`mkint` calculates the first moments of basis functions with respect to the indepent joint density rho; `mkint2` calculates the second moments for use in `project.ssden1`.

### Value

`mkint` returns a list of five elements.

`s` | First moments of phi's.
`r` | First moments of rk's.
`s.rho` | Cross moments of phi*log(rho).
`r.rho` | Cross moments of rk*log(rho).
`var.type` | Types for variables.

`mkint2` returns a list of three elements.

`ss` | Second moments of phi's.
`sr` | Cross moments of phi's and rk's.
`rr` | Second moments of rk.
