[datatable-help] How to calculate the minimum standard deviation?

[quique3716]

Dear users,

Given the vectors A and B,

A = c(8692,8654,8758,8813,8637,8381,8428,8501,8321,8033)
B = c(4,3.896,3.906,3.859,3.707,3.52,3.595,3.719,3.648,3.47)

How can I find the value of number n that gives the minimum standard
deviation value according to:

sd(A-n*B)

Thank you very much in advance
