# kernhaz

The goal of kernhaz is to estimate the unconditional and the
conditional hazard function for right-censored data. The package
includes two methods of the bandwidth selection - crossvalidation and
maximum likelihood method.

## Installation

You can install the released version of kernhaz from CRAN with:

`install.packages("kernhaz")`

## Example

The unconditional hazard function, the bandwidth is selected using
the crossvalidation method:

```
library(survival)
fit1<-khazard(times = lung$time,delta = lung$status-1)
plot(fit1)
```

The unconditional hazard function, four bandwidths are
considered:

```
library(survival)
fit2<-khazard(times = lung$time,delta = lung$status-1,h=c(100,150,200,250), value="both")
plot(fit2,h=200)
```

The conditional hazard function, bandwidths are selected using the
crossvalidation method:

```
library(survival)
fit3<-khazardcond(times = lung$time,delta = lung$status-1,covariate = lung$age)
plot(fit3)
```

The conditional hazard function, bandwidths are userâ€™s choice:

```
library(survival)
fit4<-khazardcond(times = lung$time,delta = lung$status-1,covariate = lung$age,h=c(200,20))
plot(fit4)
```
