Counting number of common elements between the rows of two different matrices
Hello
I'm trying to solve this problem without using a for loop but I have so
far failed to find a solution.
I have two matrices of K columns each, e.g. (K=5), and with numbers of
row N_A and N_B respectively
A = (1 5 3 8 15;
2 7 20 11 13;
12 19 20 21 43)
B = (2 6 30 8 16;
3 8 19 11 13)
(the actual matrices have hundreds of thousands of entry, that's why I'm
keen to avoid "for" loops)
And what I need to do is to apply a function which counts the number...

clogit and general conditional logistic regression
...e sort of
data which arise in survival/proportional hazard applications.
My question is: is 'clogit' capable of a general conditional
logistic analysis?
E.g. given a set of data on binomial experiments with Y=1
r_i times out of n_i, associated with levels A_i and B_i
of factors A and B at N_A and N_B levels, would
clogit(Y ~ A+B, method=c(Exact"))
generate something sensible containing the results of a standard
exact conditional logistic regression of Y on A and B?
With thanks,
Ted.
