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: https://en.wikipedia.org/wiki/Linear_prediction 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...
