Five carnation cultivars (‘Grand Salam’, ‘Nelson’, ‘Kaly’, ‘Cinderella’ and ‘Tempo’) were evaluated with respect to growth, yield and quality characteristics under lath house conditions at Kala Shah Kaku Research Station, Directorate of Floriculture, Lahore during 2011. Among the cultivars studied, maximum plant height was recorded in carnation cultivar ‘Grand Salam’ (78.66 cm) closely followed...

let be a random sample from a normal distribution with unknown mean and known variance the usual estimator of the mean, i.e., sample mean is the maximum likelihood estimator which under squared error loss function is minimax and admissible estimator. in many practical situations, is known in advance to lie in an interval, say for some in this case, the maximum likelihood estimator changes and d...

In this paper we propose an estimator of the entropy of a continuous random variable. The estimator is obtained by modifying the estimator proposed by Vasicek (1976). Consistency of estimator is proved, and comparisons are made with Vasicek’s estimator (1976), van Es’s estimator (1992), Ebrahimi et al.’s estimator (1994) and Correa’s estimator (1995). The results indicate that the proposed esti...

This paper investigates several strategies for consistently estimating the so-called Hurst parameter H responsible for the long-memory correlations in a linear class of ARCH time series, known as LARCH(1) models, as well as in the continuous-time Gaussian stochastic process known as fractional Brownian motion (fBm). A LARCH model’s parameter is estimated using a conditional maximum likelihood m...

nelson's syndrome is usually characterized by hyperpigmentation, elevated level of acth, and pituitary adenoma, which is frequently available as macroadenoma. it is usually occurred in the patients suffering from cushing's syndrome. growth of tumor has been revealed in 10-30% of the patients following adrenalectomy. tumors are often benign in nelson's syndrome. the selected treat...
