The argument 'K' is missing since you are only passing four arguments to the phi() function, but you defined it with five formal parameters. It looks like the argument 'j' is not necessary in the function. It is an unnecessary carry-over from the summation notation and it is never used in the function.

Hi T., Your translation of the formula looks okay, and the error message is about a missing argument. Perhaps you have not included the necessary arguments to "phi" in the call to "mls".

My formula so far looks as follows: phi <- function(w1, w2, j, k, K){ zaehler <- (k/K)^(w1-1)*(1-k/K)^(w2-1) nenner <- sum( ((1:K)/K)^(w1-1)*(1-(1:K)/K)^(w2-1)) return( zaehler/nenner ) } Unfortunately something must be wrong here as I get the following message when running a midas regression m22.phi<- midas_r(rv~mls(rvh,1:max.lag+h1,1,phi), start = list(rvh=c(1,1))) Error in phi(c(1, 1), 44L, 1) : argument "K" is missing, with no default Called from: .rs.breakOnError(TRUE) Browse[1]> K<-125 Browse[1]> 125 Could anybody look into my phi formula and tell me what is wrong with it?
