Bom dia, poderia indicar o caminho para a função interp_flatforward()? Não encontrei no código tal como a de Svensson/Nelson Siegel.

Voce chegou a bater com a curva da b3? Para o dia 10/31/22 a interpolação que eu obtive pelo método usando a função gerou mais divergência que reproduzindo no Excel o Flatforward do manual de curvas da B3. A curva fita bem, mas possui mais pontos com até 1 bp de diferença do que fazendo o processo no visual Basic, por exemplo.
