Term Structure and Credit Spread Estimation with Cubic Splines Method

Description

Term structure and credit spread estimation with cubic splines method

Usage

splines_estim(group,
              bonddata,
              matrange = "all")

Arguments

group vector defining the group of bonds used for the estimation,newline e.g. c("GERMANY","AUSTRIA")
bonddata a dataset of bonds in list format
matrange use "all" for no restrictions, or restrict the maturity range used for the estimation with c(lower,upper)

Details

group
The first element of the vector will be used as the reference country for the credit spread estimation. The group can be either a vector of groups or a scalar.
bonddata
The package is tailored to the included data sets. Therefore the structure and the naming convention of other used data sets has to be identical. Use the function str() to explore the structure of the provided datasets.

Value

The function splines_estim returns a list with the following elements or sub-lists:

group groups used from data set
matrange maturity range
n_group the number of groups used for the optimisation
zcy_curves values for plotting the estimated zero-coupon yield curves
scurves values for plotting the spread curves
cf cashflows matrix for all specified groups
m maturity matrix for all specified groups
duration duration, weighted duration and duration based weights
p dirty prices
phat estimated bond prices
y bond yields
yhat theoretical bond yields calculated with the estimated bond prices phat
alpha OLS coefficients of cubic splines estimation
