First-Order Multi-Compartment kinetics

+ Source: R/parent_solutions.R +
FOMC.solution.Rd
+
+ +
+

Function describing exponential decline from a defined starting value, with +a decreasing rate constant.

+
+ +
+

Usage

+ 
FOMC.solution(t, parent_0, alpha, beta)
+
+ +
+

Arguments

+ + +
t
+

Time.

+ + +
parent_0
+

Starting value for the response variable at time zero.

+ + +
alpha
+

Shape parameter determined by coefficient of variation of rate +constant values.

+ + +
beta
+

Location parameter.

+ +
+
+

Value

+

The value of the response variable at time t.

+
+
+

Details

+

The form given here differs slightly from the original reference by +Gustafson and Holden (1990). The parameter beta corresponds to 1/beta +in the original equation.

+
+
+

Note

+

The solution of the FOMC kinetic model reduces to the +SFO.solution for large values of alpha and beta +with \(k = \frac{\beta}{\alpha}\).
