The purpose of this study is to reduce the uncertainty of early stage startups success prediction and filling the gap of previous studies in the field, by identifying and evaluating the success variables and developing a novel business success failure (S/F) data mining classification prediction model for Iranian start-ups. For this purpose, the paper is seeking to extend Bill Gross and Robert L...

Accelerated life tests (ALTs) are widely used in many applications for the time-effective assessment of products. Statistical analysis of the performance degradation paths of the products combined with actual failure times have the competence to provide more accurate lifetime estimates. We propose two nonparametric methods for analyzing the ALT data where the degradation paths and failure times...

BACKGROUND To reduce nursing shortages, accelerated nursing programs are available for domestic and international students. However, the withdrawal and failure rates from these programs may be different than for the traditional programs. The main aim of our study was to improve the retention and experience of accelerated nursing students. METHODS The academic background, age, withdrawal and f...

We provide new conditions for identification in accelerated failure time competing risks models. In our model, we specify unknown regression functions and the joint survivor function of latent disturbance terms nonparametrically. We show that the model can be identified with covariates that are independent of latent errors, provided that certain rank conditions are satisfied. We present a simpl...

There is an increasing interest in life-course epidemiology (Ben-Shlomo 2007; Ben-Shlomo and Kuh 2002), with the quantification of the effects of exposures over long periods of time. For example, several papers recently have examined the effects of socioeconomic position at different stages of life, and changes in that exposure between these stages, on outcomes including risk of stroke and resp...

BACKGROUND The prognosis of patients with chronic myelogenous leukemia (CML) after failure of imatinib mesylate therapy is not well documented. METHODS The outcome of 420 patients with CML post-imatinib failure (resistance-recurrence in 374; toxicities in 46) were reviewed in relation to survival, overall, and by different therapies. RESULTS The estimated 3-year survival rates were 72% in 8...

The reliability and failure modes of molar crowns supported by three different implant-supported designs were tested according to the following groups: group 1, one standard-diameter implant (3.75 mm); group 2, one narrow-diameter implant (3 mm); and group 3, two narrow-diameter implants (3 mm). Loads were applied as mouth-motion cycles using a step-stress accelerated life-testing method. ? val...
