The proportional hazard Cox regression models play a key role in analyzing censored survival data. We use penalized methods in high dimensional scenarios to achieve more efficient models. This article reviews the penalized Cox regression for some frequently used penalty functions. Analysis of medical data namely ”mgus2” confirms the penalized Cox regression performs better than the cox regressi...

In the financial world, importance of “downside risk” and “higher moments” has been emphasized, predominantly in developing countries such as Pakistan, for a substantial period. Consequently, this study tests four models suitable capital asset pricing model. These are CAPM’s beta, beta replaced by skewness (gamma), with gamma, downside CAPM (DCAPM), gamma. The problems high correlation between ...

The data were collected by means of Young early maladaptive schemas questionnaire (lo...

Quinoa (Chenepodium quinoa Willd.) is a grain-like crop which has a high potential of crop yield under arid environments. The objective of this study was to evaluate the responses of seed germination rate and percentage to temperatures and estimate cardinal temperatures in three quinoa cultivars (i.e., Sajama, Titicaca and Santamaria). Germination of quinoa seeds were daily counted at the tempe...

A new and flexible distribution is introduced for modeling proportional data based on the quantile of generalized extreme value distribution. We obtain explicit expressions moments, quantiles, other structural properties. An extended regression model constructed as an alternative to compete with beta regression. Some simulations from Bayesian perspectives are developed, illustrative application...
