Hi everybody,
I am trying to generate the formula shown in the attachment. 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?
Thanks in advance.

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".

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.

Your function phi has 5 arguments with no defaults. Your call only has 3 arguments. Hence the error message.> 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 ) + }> phi(c(1, 1), 44L, 1)Error in phi(c(1, 1), 44L, 1) : argument "k" is missing, with no default>"T.Riedle" <tr206 at kent.ac.uk> Sent by: "R-help" <r-help-bounces at r-project.org> 03/29/2015 08:59 AM To "r-help at r-project.org" <r-help at r-project.org>, cc Subject [R] generating phi using function() Hi everybody, I am trying to generate the formula shown in the attachment.
