sumvalpr {ibr} | R Documentation |
Sum of a geometric series
Description
Calculates the sum of the first (k+1) terms of a geometric series with initial term 1
and common ratio equal to valpr
(lower or equal to 1).
Usage
sumvalpr(k,n,valpr,index1,index0)
Arguments
k |
The number of terms minus 1. |
n |
The length of |
valpr |
Vector of common ratio in decreasing order. |
index1 |
The index of the last common ratio equal to 1. |
index0 |
The index of the first common ratio equal to 0. |
Value
Returns the vector of the sums of the first (k+1) terms of the geometric series.
