lscv.exact {locfit} | R Documentation |

## Exact LSCV Calculation

### Description

This function performs the exact computation of the least squares cross validation statistic for one-dimensional kernel density estimation and a constant bandwidth.

At the time of writing, it is implemented only for the Gaussian kernel (with the standard deviation of 0.4; Locfit's standard).

### Usage

```
lscv.exact(x, h=0)
```

### Arguments

`x` |
Numeric data vector. |

`h` |
The bandwidth. If |

### Value

A vector of the LSCV statistic and the fitted degrees of freedom.

### Examples

```
data(geyser, package="locfit")
lscv.exact(lp(geyser,h=0.25))
# equivalent form using lscv
lscv(lp(geyser, h=0.25), exact=TRUE)
```
