Computes implied rates to compounding factors.

implied_rate(x, t, val, ...)

Arguments

x

a Compounding object or a character with the compounding name.

t

a numeric representing the term.

val

a numeric representing the compounding factor.

...

additional arguments. Currently unused.

Value

A numeric value that represents a spot rate.

Details

If the x argument is a character with a valid compounding name (simple, discrete, continuous) the function instanciates a Compounding object and then computes the implied rate for the given compounding values and terms.

Examples

implied_rate("simple", 2, 1.1)
#> [1] 0.05
implied_rate("discrete", 2, 1.1025)
#> [1] 0.05
implied_rate("continuous", 2, 1.105170918)
#> [1] 0.05

comp <- compounding("discrete")
compound(comp, 0.06, 2) # equals (1 + 0.06) ^ 2 = 1.1236
#> [1] 1.068138
implied_rate(comp, 1.1236, 2) # equals 0.06
#> [1] 0.8531716
