Anaemia is the common problem during pregnancy in developing countries like Nepal. A total of 200 stool samples for parasitic infection and their haemoglobin level data were collected from the pregnant women visiting TUTH. The overall prevalence of intestinal parasitic infection and anaemic rate among pregnant women was found to be 35% and 50%. Among 100 anaemic pregnant women 58 women were infected with intestinal parasites. The association of anaemia with intestinal parasitic infection was statistically significant (P > 0.05). The most dominant parasite among anaemic pregnant women was A. lumbricoides followed by H. nana. Total five different types of intestinal parasites were identified in this study. Among them A. lumbricoides (30.5%), H. nana 6(3%), E. histolytica 5(2.5%), T. trichiura 2(%) and S. stercoralis 2(1%) respectively. Pregnant women with single parasitic infection were found to be 64(32%) and multiple infection were 6(3%). Intensity of parasitic infection found to be 17(8.8%), 34 (17.0%) and 17 (9.5%) for light, moderate and heavy infection.
This study proposes new distribution which is generated from exponentiated-exponential-X family of distribution. It is explored various shape and behavior of the observed distribution through probability density plot, hazard rate function and quantile function. Further we have investigated some mathematical properties, estimation of the parameters and associated confidence interval using maximum likelihood estimation (MLE) method of the exponentiatedexponential-logistic distribution (EELD).
In this work, a novel distribution called an inverted shifted Gompertz distribution by the inverse transformation method is introduced and studied. Some relevant characteristics of inverted shifted Gompertz distribution are mathematically and statistically discussed. To estimate parameters of an inverted shifted Gompertz distribution, some well-known estimation methods, namely LSE, MLE and CVME are used. R software is applied for computational purposes. The applicability of the proposed model has been illustrated considering a real set of data and investigated the goodness-of-fit attained by the inverted shifted Gompertz model through various test statistics and graphical methods. We found that the proposed novel distribution is more flexible and delivered a better fit in contrast with some other selected lifespan models.
We have defined a novel three-parametric model having bathtub- shaped hazard rate curve called a modified NHE distribution in this study. Several statistical features of recommended model are explicitly derived. Least square, maximum likelihood and Cramer-Von-Mises are three renowned estimations approaches which can be applied to derive model parameters. The estimators' asymptotic confidence intervals are also defined. The suggested distribution's goodness of fit is evaluated through a real data set. On real -world data set, we have discovered that the innovative suggested model outperforms other competitive models.
In this article, we have introduced a new probability distribution having three parameters using half Cauchy family of distribution named half Cauchy extended exponential distribution. The statistical properties and characteristics of the proposed distribution like the hazard rate function (HRF), cumulative hazard function, and the probability density function (PDF), and the cumulative distribution function (CDF), quantile function and the skewness, kurtosis are provided. The parameters of the proposed distribution are estimated using the Cramer-Von-Mises (CVM) least-square estimation (LSE), and maximum likelihood estimators (MLE) methods. A real data set is analyzed to test the goodness-of-fit of the proposed distribution. It is found that the half Cauchy extended exponential distribution performed well as compared to some competing distributions.
