Sentence examples for guess parameters from inspiring English sources

Moreover, as a variation-based method, we find that the convergence and the synthesized results of the LMO method are strongly dependent on the initial guess parameters.

Therefore, the "first guess" parameters must be relatively close to those of the best fit.

Using the data points x ^ i (t j ) to generate a suitable initial guess, parameter estimation may proceed via a nonlinear programming approach (see Methods, Additional file 1).

The estimated discrimination and guessing parameters were almost identical with and without removing the rapid guesses from IRT modeling.

That is, the addition of guessing parameters and multidimensional simple structures only lead to very small improvements in fit.

Their testlet model can be extended to 2-parameter and 3-parameter IRT testlet models for DIF detection by including discrimination and guessing parameters.

Anderson's approach is appropriate for understanding the impact of time on the ability distribution and for reviewing the characteristics of the test by time, Andrade and Tavares (2005) extended Anderson's model to 2PL and 3PL IRT models, which include item discrimination and item guessing parameters, respectively.

More complex models include the estimation of item discrimination and guessing parameters (2PL and 3PL models).

Because the "I don't know" choice was included for all questions, guessing parameters were not considered.

However, item discrimination and guessing parameters should ideally be evaluated via a full two-parameter logistic model, rather than estimated using the more constrained Rasch model.

Given the capacity, lapse, and guessing parameters, the true hit and false alarm rates may be computed using the multinomial trees in Fig.  3.
