## Description

Generates a lag one auto-regressive time series, where the first and last
values are fixed. Marginal expected value is zero and variance is one.
Generated values have a normal conditional distribution.

## Usage

genmissing(X1, XN, rho, N)

## Value

genmissing numeric vector of length N, conditioned on the
first value (X1) and last value (XN) with the specified lag one autocorrelation
in the limit (where N is large) the values are normal with mean 0 and variance 1

## Arguments

- X1
value before the gap

- XN
value after the gap

- rho
the lag one autocorrelation

- N
the length of the sequence including X1 and XN. It
is two more than the gap length
