To make them active, include a library statement at the top of your program. All software modules that were available on Quarry are available on Karst. You may also want to disable the keyboard control of the nested versions. If it is going to analyze a different data set from the outer version then pass it the data set name in a string.

ARCHIVED: At IUB, in GAUSS, how can I access the application libraries?
The procedure must have two input arguments, first, a vector of parameter values, and second, one or more rows of the data matrix. All software modules that were available on Quarry are available on Karst. This is document adea in the Knowledge Base. Significant librray in computation time may be achieved when the data set can be stored in memory and procedure is written to compute vectors of log-probabilities.
GAUSS's Maximum Likelihood Procedure
Variable selection as opposed to case selection can be done on any level through the second argument in the call to each version of MAXLIK. You may also load and store a data set in memory in the command file and pass it as the first argument in the nested call to MAXLIK. Research Maxlok is located on the IU Bloomington campus at Woodburn Hall ; staff are available for consultation Monday-Friday 9am-noon and by appointment. GAUSS provides several application libraries add-on modules in addition to the base program.
The output argument is the log-likelihood for the observation or observations in the second argument evaluated at the parameters values in the first argument.
Maximum Likelihood Module
User data on Quarry has not be removed; you can access your old home directory data on Quarry from your account on any other IU libraru computing resource see Available access to allocated and short-term storage capacity on IU's research systems. If it is going to analyze a different data set from the outer version then pass it the data set name in a string.

IU students, gaus, and staff can request accounts on KarstIU's newest high-throughput computing cluster; for instructions, see Requesting an account. You may also want to disable the keyboard control of the nested versions. The third line is to reset the global variables in succeeding executions of your program.

If a data set is being analyzed and it is to be transformed or deleted for missing data or cases are to be selected, then this can be done only on the outermost version of MAXLIK, i.
For example, if you want to use the maximum likelihood procedures, include the following lines at the top of lbirary program:. After seven years of production service, Indiana University's Quarry research computing cluster was decommissioned January 30, Last modified on If you have questions about using statistical and mathematical software at Indiana University, contact Research Analytics.
If you have questions or concerns about Ilbrary retirement, or need help, contact the High Performance Systems group. To make them active, include a library statement at the top of your program. The gausw must provide a procedure for computing the log-likelihood for either one observation, or for a matrix of observations. You must not use MAXSET because that will clear information about the data sets opened and processed in the outer version.
The following modules are available:. In order to use any of the application modules, the libraries required by the modules must be active.
