I am attempting to run a Poisson EWMA model using Patrick Brandt's source code. I get the following error when I run the code:
Error in dimnames(x) <- dn : length of 'dimnames' [1] not equal to array extent Dimnames(x) looks like this: [[1]] NULL [[2]] [1] "mip" "div" "nom" "unity" "mood" "times" [7] "hmajparty" "smajparty" "pres" It seems to me that the NULL value here is causing the problem but I can't figure out (1) why the null value is showing up and (2) how to get rid of it. Background code is as follows: cr.pois<- glm(countlaw ~ mip + div + nom + unity + mood + times + hmajparty + smajparty + pres, family = poisson) summary(cr.pois) init <- coef(cr.pois) x<- cbind(mip,div,nom,unity,mood,times,hmajparty,smajparty,pres) cr.PEWMA<- Pewma(y=countlaw,x=as.matrix(x),init.param=c(0.8,init[2:length(init)])) Which results in this output: N = 10, M = 5 machine precision = 2.22045e-16 iterations 34 function evaluations 45 segments explored during Cauchy searches 35 BFGS updates skipped 0 active bounds at final generalized Cauchy point 1 norm of the final projected gradient 0.00806577 final function value 1.78439 final value 1.784390 converged Error in dimnames(x) <- dn : length of 'dimnames' [1] not equal to array extent Any thoughts on what's going on here and how to fix it?
