ratioBeta: The ratio of two beta functions.
In MobilePhoneESSnetBigData/pestim: Population Estimations Using Mobile Phone Data

Compute the ratio of two beta functions whose arguments differ by integer numbers

1	ratioBeta(alpha, beta, m, n)

`alpha,`	beta non-negative numeric vectors
`m,`	n non-negative integer vectors

ratioBeta gives \frac{B(alpha + m, beta + n)}{B(alpha, beta)}

The lengths of the input vectors must be all equal except when their length is 1, which are recycled. Otherwise NAs are produced.
