To start let’s look at the simplest model, known as a linear regression:In this model we have the following: y = the dependent variable (i.e. what you measure as the signal) x = the independent variable (i.e. what you control, such as, dose, concentration, etc.) ...
In recent years, interest in the four-parameter logistic (4PL) model (Barton and Lord, ETS Res Rep Ser 198(1):i-8, 1981), and its normal ogive equivalent, has been renewed (Culpepper, Psychometrika, 81(4):1142–1163, 2016; Feuerstahler and Waller (Multiv
The new model was implemented in GAMLSS package of R software and a brief tutorial on how to use this package is presented throughout the paper. We provide a comprehensive treatment of its general mathematical properties. Further, we propose a new extended regression model considering four ...
Application of the Parametric Regression Model with the Four-Parameter Log-Logistic Distribution for Determining of the Effecting Factors on the Survival Rate of Colorectal Cancer Patients in the Presence of Competing RisksBackground: In competing risks data, when a person experiences more than one ...

Thus, we purpose a new flexible Be-ta Four Parameter Generalized Mixed Effect Tree and Random Forest predic-tion model that combines the use of tree regression and random forest with a Bayesian beta four parameter GLMM approach. This model takes into con-sideration that paddy productivity has a...
Estimates of the A parameter for Model 2 obtained by linear regression for the four branches of the AA metabolism: 5(S)-HETE, 15(S)-HETE, 11,12-DiHETrE and 14,15-DiHETrE.Edoardo, Saccenti
The relationship between PIV and short- and long-term all-cause mortality was analyzed using a multivariate Cox proportional hazard regression model and Kaplan-Meier (K-M) survival curve analysis. Interaction and subgroup analyses were also carried out. Results: The study includ...
A rheological parameters calculation model was built based on regression method. On the basis of several test data, an evaluation of the FP model with other models was made. A generalized hydraulic calculation model was developed based on the power law extension method. The predictions of the ...
