Dealing with NAs
...o estimate parameter values with mlogit. I attach a part of my data.
My code is
x=mlogit.data(y,choice="voittaja",shape="long",id.var="id",alt.var="numero")
summary(mlogit(voittaja ~ Ie-1 , data=x, na.action=na.pass))
But i get
Error in if (abs(x - oldx) < ftol) { :
missing value where TRUE/FALSE needed
Because there is Na in D2.
What should i do to make it work?

Mlogit missing value problem
...ConnectExcel("D:\\SAMBLEDATA.csv")
> y<-sqlFetch(z,"Taul1")
> x=mlogit.data(y,choice="voittaja",shape="long",id.var="id",alt.var="numero")
> summary(mlogit(voittaja ~ Fa+Ie -1 , data=x, na.action=na.pass))
Error in if (abs(x - oldx) < ftol) { :
missing value where TRUE/FALSE needed
The reason for this error is in the row 563. There the choice has value 1
and Ie has missing value.
If the choice has value 0 and Ie has missing values, then there is no errors.
What should i do to make it work..?

Matrix interesting question!
hi,
I have been trying to do this in R (have implemented it in Excel) but I have
been using a very inefficent way (loops etc.). I have matrix A (columns are
years and ages are rows) and matrix B (columns are birth yrs and rows are
ages)
I would like to first turn matrix A into matrix B
And then I would like to convert matrix B back again to the original matrix
A. (I have left out details of

right justify right-axis tick values in lattice
How can I right justify the right-axis tick values? They appear in the
example below as left-justified.
I have tried several different ways and all fail in different ways.
The example below creates the right axis tick value with no attempt at
adjustment.
alternates I have tried are
1. formatting the values. This doesn't work because they are in a
proportional font and the blanks
are too

mlogit: block design CE model
...1 2 0 1 1
I have tried the following codes to set the data for mlogit and run the
model:
T1m<-mlogit.data(T1,shape="long",choice="choice",alt.var="Alt")
m1=mlogit(choice~x1+x2+x3+x4|Age+Sex, data=T1m)
I am getting the following error:
Error in if (abs(x - oldx) < ftol) { : missing value where TRUE/FALSE
needed
I have gone through the data and found no missing values.
Please advice if the codes I have used are appropriate and what is going
wrong.
Thanks in advance,

Party package: varimp(..., conditional=TRUE) error: term 1 would require 9e+12 columns
I would like to build a forest of regression trees to see how well some
covariates predict a response variable and to examine the importance of the
covariates. I have a small number of covariates (8) and large number of
records (27368). The response and all of the covariates are continuous
variables.
A cursory examination of the covariates does not suggest they are correlated
in a simple fashion
