Algorithm 708 (BRATIO) was run on 2730 test cases. Comparison of these results with the results from an algorithm using a continued fraction of Tretter and Walster were performed using a high-precision version of the latter algorithm implemented in Maple. Accuracy of BRATIO ranged from 9.64 significant digits to a full machine double-precision, 15.65… (More)
The flexible statistical models incorporating the log-F distribution are little used because of numeric difficulties. We describe a method for calculating the log-likelihood and two derivatives with respect to the data argument. Fortran subroutines incorporating these calculations are provided.
To assess the prognostic value of neurologic function (NF) in patients with astrocytic spinal cord glioma, we conducted a retrospective study of 25 patients who were treated at our institution between January 1970 and December 1999. The median age was 40 years, and the median follow-up was 54 months. Nineteen patients had a biopsy, 5 had a subtotal… (More)
Inflammatory breast cancer (IBC) is an aggressive type of breast cancer, characterized by very rapid progression, enlargement of the breast, skin edema causing an orange peel appearance (peau d’orange), erythema, thickening, and dermal lymphatic invasion. It is characterized by E-cadherin overexpression in the primary and metastatic disease, but to date no… (More)
