replace.zeros: Replace zero's in input matrix

In mpascariu/MortalityForecast: Standard Tools to Compare and Evaluate Various Mortality Forecasting Methods

Description

If a matrix or data.frame contains death-rates equal to zero, they will be replaced with positive values.

Usage

replace.zeros(mx, method = c("min", "mult"), radix = 1e+05)

Arguments

mx	Matrix of death rates
method	Method of replacement: "min" – Replace with minimum observed value in the input dataset; "mult" – Replace using the multiplicative replacement strategy.
radix	radix. Default: 1e5.

Examples

x  <- 0:25
y  <- 2005:2016
mx <- HMD_male$mx$DNK[paste(x), paste(y)]
mx == 0

new.mx <- replace.zeros(mx)
new.mx == 0

sum(mx) == sum(new.mx)
(mx - new.mx)/mx * 100
