discrete discriminant analysis
...o predict the type of gear used. however a consistent
error is occuring:
Error in polybasis(newdata, degree, monomial) %*% object$coef :
non-conformable arguments
it is possible the problem being related with the 2 predictors that are
discrete variables?
there is already available some rotine to perform a discrete discriminant
analysis considering continuous and discrete variables?
if someone can help, would be very grateful.
cheers,
Catarina

Fitting GLMM models with glmer
...y=poisson)
After that, the authors present the same model, but now bi = log(gi)
where gi has the following gamma distribution:
f(gi | theta1) = gi ^ (1/theta1 - 1) exp(-gi/theta1)/
GAMMA(1/theta1)(theta1^(1/theta1)
They used a set of transformations proposed in the paper, and with the
following rotine fitted the model achieving
estimates for the same fixed parameters and for theta1:
proc nlmixed data=liver;
parms theta1 = 1 b0 = -2:8 btrt = -0.54 bhrt =0:18;
pi = CDF('NORMAL',ai);
if(pi > 0:999999) then pi =0:999999;
gi2 = quantile('GAMMA',pi, 1/theta1);
gi = theta1 * gi2;

Hi,
I installed the package r-cran-lmtest in a Debian Sid but I can't use it. I typed "lmtest" but nothing occur.

Probability(Markov chain transition matrix)
Hello, My name is Maria, MBA student in Sanfransisco, USA.
In my credit scoring class, I have hard time making "transition matrix",
which explains probability especially in relation to "Markov chain model".
It is regarding people's monthly credit payment behavior. Does R have
function to caculate it? I am actually a novice in using 'R'. Please help
me!!!

prediction problem
...predict the color. However a consistent error is
occuring:
****Error in mindist[l] <- ndist[l] :
******NAs are not allowed in subscripted assignments
It is possible the problem being related with the 2 predictors that are
discrete/categorical variables?
There is already available some rotine to perform a discriminant analysis
considering continuous and discrete/categorical variables?
If someone can help, would be very grateful.
cheers,
Catarina
