Confusion about linear prediction within flac
Hi,
I'm researching lossless compression for a highschool mathematics
research essay and am fairly confused about how the linear prediction
coefficients are solved for within flac.
As far as I understand, Levinson Durbin Recursion is used to solve for
these coefficients, however, what I don't understand is what the
toeplitz matrix is composed of. I found sources using samples from
within

The Wikipedia page on this subject is not terrible:

The very high-level answer is that if want to choose your coefficients
to minimize the mean squared error of

Output predictions based on a Cox model
Hi,
I've generated a cox model, but I'm struggling to work out how to output
predctions based on the model I've made.
my.model<-coxph(Surv(duration,status) ~ gender + var1 + var2,
data=mydata)
My test data set looks something like this:
id,actualduration,gender,var1,var2
a,65,m,1,3
b,34,f,1,5
...
What i need to do is for each id, output a predicted duration based on
my cox...
