kannisto.estimate {MortCast}

Kannisto Estimation

Description

Estimate the Kannisto parameters (Thatcher et al. 1998).

Usage

kannisto.estimate(mx, ages)

Arguments

mx

A vector of mortality rates.

ages

A vector of ages corresponding to mx. These can be indices of age groups or raw ages.

Details

Given the Kannisto equation logit(m_x) = \log(c) + dx, the function estimates the c and d parameters using values of ages as the covariate x.

Value

List with the following components:

coefficients:

named vector with Kannisto coefficients c and d.

fitted.values:

the fitted values

residuals:

input rates minus the fitted values
