lscvplot {locfit} | R Documentation |

## Compute the LSCV plot.

### Description

The `lscvplot`

function loops through calls to the `lscv`

function (and hence to `link{locfit}`

), using a different
smoothing parameter for each call.
The returned structure contains the LSCV statistic for each density
estimate, and can be used to produce an LSCV plot.

### Usage

lscvplot(..., alpha)

### Arguments

`...` |
arguments to the `lscv` , `locfit`
functions. |

`alpha` |
Matrix of smoothing parameters. The `lscvplot` function
loops through calls to `lscv` , using each row of
`alpha` as the smoothing parameter in turn. If `alpha`
is provided as a vector, it will be converted to a one-column
matrix, thus interpreting each component as a nearest neighbor
smoothing parameter. |

### Value

An object with class `"gcvplot"`

, containing the smoothing
parameters and LSCV scores. The actual plot is produced using
`plot.gcvplot`

.
