| NSrates {YieldCurve} | R Documentation |
Returns the interest rates by Nelson-Siegel's model.
NSrates(betaCoeff, lambdat, maturity)
betaCoeff |
vector or matrix of the beta's coefficients. |
lambdat |
value of the estimated lambda |
maturity |
maturity of the yield curve of which want to return the interest rates. |
betaCoeff is a vector or matrix of the three coefficients of the Nelson-Siegel's model
Return interest rates in matrix object with number of rows equal to nrow(betaCoeff) and number of columns equal to length(maturity).
