The NLMOD Procedure
PROC NLMOD Features
The NLMOD procedure does the following:
is highly multithreaded during all phases of analytic execution
computes analytical derivatives of user-provided expressions for more robust parameter estimations
evaluates user-provided expressions and their confidence limits by using the ESTIMATE and PREDICT statements
estimates parameters without specifying a particular distribution function by using the least squares method
estimates parameters by using the maximum likelihood method when either a built-in distribution function is specified or a likelihood function is provided
Because the NLMOD procedure runs on CAS, it also does the following:
enables you to run in distributed mode on a cluster of machines that distribute the data and the computations
enables you to run in single-machine mode on CAS
exploits all the available cores and concurrent threads, regardless of execution mode. For information about how PROC NLMOD uses threads, see the section Multithreading in Chapter 3: Shared Concepts.
