Detailed Description

Defines data types used by etirm.

Data types representing floating point numbers, vectors and matrices of floating point numbers, and examinee item responses.

Some types are used from the Simple C++ Numerical Toolkit (SCPPNT). SCPPNT is available from http://www.smallwaters.com/software/cpp/scppnt.html.

Estimation Toolkit for Item Response Models (ETIRM) http://www.smallwaters.com/software/cpp/etirm.html

Define Documentation

#define ETIRM_FLOAT_TYPE   double

This definition describes the default data type used for floating point numbers. \.

It defaults to double, but can be overriden at compile time redefining ETIRM_FLOAT_TYPE, e.g.

g++ -DETIRM_FLOAT_TYPE='float' ...

Definition at line 37 of file etirmtypes.h.

#define ETIRM_RESPONSE_TYPE   char

This definition describes the default data type used for an item response and covariant for an examinee.

It defaults to char, but can be overriden at compile time redefining ETIRM_RESPONSE_TYPE, e.g.

g++ -DETIRM_RESPONSE_TYPE='int' ...

Definition at line 51 of file etirmtypes.h.
