modified.exp.lower.inv: Modified exponential function with lower bound

In tkmckenzie/ikde: Iterative Kernel Density Estimation

Description

Modified exponential function with lower bound

Usage

modified.exp.lower.inv(x, lower.limit = 0)

Arguments

x	Point to evaluate modified exponential function and gradient
lower.limit	Lower limit of the modified exponential function; defaults to 0

Details

Evaluates the inverse modified exponential function (log(x - lower.bound)) and its gradient (1 / (x - lower.bound)).

Value

Returns a list with two elements, each with the same number of elements as x

value	Value of the inverse modified exponential function at x
gradient	Value of the gradient of the inverse modified exponential function at x

Examples

x <- seq(0.005, 5, length.out = 100)
exp.result <- modified.exp.lower.inv(x)

plot(exp.result$value ~ x, type = "l")
plot(exp.result$gradient ~ x, type = "l")
