The Exponentiated Generalized NH Distribution
Nadarajah and Haghighi (2011) introduced a new generalization of the exponential distribution as an alternative to the gamma, Weibull and exponeniated exponential distributions. In this paper, a generalization of the Nadarajah– Haghighi (NH) distribution namely exponentiated generalized NH distribution is introduced and discussed. The properties and applications of proposed model to real dat...
متن کاملEfficient Estimation of the Density and Cumulative Distribution Function of the Generalized Rayleigh Distribution
The uniformly minimum variance unbiased (UMVU), maximum likelihood, percentile (PC), least squares (LS) and weighted least squares (WLS) estimators of the probability density function (pdf) and cumulative distribution function are derived for the generalized Rayleigh distribution. This model can be used quite effectively in modelling strength data and also modeling general lifetime data. It has...
متن کاملThe new generalized inverse Weibull distribution
Failure rate is one of the important concepts in reliability theory. In this paper, we introduce a new distribution function containing four parameters based on inverse Weibull distribution. This new distribution has a more general form of failure rate function. It is able to model five ageing classes of life distributions with appropriate choice of parameter values so that it is displayed decr...
متن کاملThe Type I Generalized Half Logistic Distribution
In this paper, we considered the half logistic model and derived a probability density function that generalized it. The cumulative distribution function, the $n^{th}$ moment, the median, the mode and the 100$k$-percentage points of the generalized distribution were established. Estimation of the parameters of the distribution through maximum likelihood method was accomplished with the aid of c...
متن کاملSome Properties of Generalized Age-Distribution Equations in Fluid Dynamics
The concept of age in fluid dynamics is analyzed in the case of a tracer advectiondiffusion equation. From the general solution in a uniform velocity field, it is shown that unexpected symmetry properties arise for the age field. In particular, for a point release, the age field is isotropic, regardless of the direction of the flow and the value of the diffusion coefficient. The analysis is the...
