Calculate the ratio of standardized death rates and its confidence interval.

1	std.rate.ratio(count, pop, stdcount, stdpop, conf.level = 0.95)

`count`	vector of age-specific cohort deaths
`pop`	vector of age-specific cohort population or person-years
`stdcount`	vector of age-specific standard population deaths
`stdpop`	vector of age-specific standard population
`conf.level`	confidence level as a number between 0 and 1. Default is 0.95.

a list with the following components:

Standardized rate ratio: The ratio of the standardized death rates
CI: The confidence interval for the standardized rate ratio
Crude rate ratio: The ratio of the crude cohort death rate to the standard population death rate
directly standardized death rate: The weighted average of the cohort age-specific death rates
