Varying coefficients model with measurement error.

We propose a semiparametric partially varying coefficient model to study the relationship between serum creatinine concentration and the glomerular filtration rate (GFR) among kidney donors and patients with chronic kidney disease. A regression model is used to relate serum creatinine to GFR and demographic factors in which coefficient of GFR is expressed as a function of age to allow its effec...

Measurement of the correlation coefficients between extracted features from CT and MR images

Introduction: Nowadays applying computer in image processing is being improved revolutionary for solving medical images deficiencies. Image features that are analysis in image processing show image information. The aim of the present study was to find correlation between CT- scan and MRI images' features. Materials and Methods: After data acquisition, applying...

A MEASUREMENT OF pp SPIN CORRELATION COEFFICIENTS AT

Data taking for CE42 was completed in February 1996. The experiment utilized the Wisconsin/IUCF polarized target1 which has been used by CE35 to measure spin correlation coefficients in pp elastic scattering at 200 MeV at angles 10" 5 O,, 5 35" [Ref. 21. The target cell and detector system are shown in Fig. 1. For ease of tuning and to be less susceptible to shifts in beam position during eithe...
