Abstract
In this paper, a Cubic Transmuted Kappa distribution (CTKD) to expand the work of cubic transmuted distribution families CTKD increases the ability of the transmuted distributions to be flexible and facilitate the modelling of more complex data. Some statistical properties of CTKD are discussed. To estimate the parameters for model, the maximum likelihood estimation technique in order to appear the interest of the Cubic Transmuted Kappa Distribution, two real datasets are used to examine the ability to apply it and to observe the performance of estimation techniques on CTKD, Kappa and transmuted Kappa distributions. The observed results showed that CTKD gives better fit than Kappa and transmuted Kappa distributions for the applied data sets.

1. Introduction
The Statistical Researcher faces many statistical difficulties during the,development of analyzing the data as well as Estimating the parameters related to the distribution, and among those problems that the researcher,directs is the process of determining the, appropriate and appropriate,distribution of the data singularity. The Researchers Specialized in the ground specialized in the Statistical field have functioned to progress, the Probability Distributions and move them to,the phase of the Transformed probability Distributions, in order to obtain, the best representation of the data with the least errors, Particularly,when the Researcher appearances the Problem of Choosing The,Sample With an Equal Probability, which Made The Original Distribution Limited to the Modelling of Phenomena It is unserviceable and when it develops necessary, to suggest a Specific Modification to be Done finished the Transformed System in Order to Obtain, Vocabulary That Has The Same Appearance of Accidents, " now a Days Transmuted Distributions And Their Mathematical Properties are Widely Studied For Applied Sciences Experimental Data Sets. transmuted rayleigh distribution (merovci, 2013) [13], Transmuted Inverse, Rayleigh Distribution (Ahmad et al., (2014) [2], Transmuted Generalized Inverse weibull distribution (khan and king, 2013) [9], transmuted modified inverse weibull distribution (elbatal, 2013) [8], transmuted log-logistic distribution (aryal, (2013) [4], transmuted modified weibull dsistribution & transmuted lomax distribution (ashour Aand eltehiwy, (2013) [5], transmuted frechet "distribution (mahmoud & mandouh, (2013) [12], transmuted pareto distribution (merovci & puka,( 2014), transmuted generalized gamma distribution (lucena et al., (2015) [11], transmuted weibull lomax distribution (afify et al.,( 2015) [1] are reported with their various structural properties including explicit expressions for the Moments, Quantiles, Entropies, Mean Deviations And Order Statistics. all the Above Transmuted Distributions are Derived By Using quadratic Rank transmutation map(qRTM) Studied By Shaw & Buckley (2007) [16]. Report reveals that some properties of these distributions along with their parameters Are Estimated By Using Maximum Likelihood And bayesian Methods. usefulness Of some of These New Distributions Are Also illustrated With Experimental Data Sets. transmuted gumbel distribution (tGD) Along With Several Mathematical Properties Has Studied By aryal and tsokos (2009) [3] Using quadratic rank transmutation map(qRTM)and Reported That( TGD) Can be Used to Model Climate Data. Therefore an Attempt Has Been Made to Developed transmuted exponentiated gumbel distribution (tEGD) Using exponentiated Gumbel distribution (EGD),and The quadratic rank transmutation map(qRTM). the parameters of The (TEGD) are Estimated by The Method Of Maximum Likelihood and Applied to The Water Quality Parameter Data Sets For Study The Usefulness Of The Model.
A Random Variable X is Said to Have a Cubic Transmuted Distribution if its Cumulative Distribution Function (CDF) is Given By:
Where G(x) is the CDF of The Cubic Transmuted Distribution and F(x) is the CDF OF The base Distribution. differentiating (1) it Gives The Probability Density Function (PDF) of The Transmuted Distribution as Zhao& Lu,. (2008) [17]:

4. Application of Cubic Transmuted Kappa Distribution
"We compare our proposed distribution with the new cubic transmuted Kappa distribution, Kappa distribution. (khan and king, 2013) [9] Here. By utilizing the maximum likelihood method, we estimate distribution parameters. The goodness of fit measures including the minus log-likelihood function (-LL), Akaike information criterion (AIC), Bayesian information criterion (BIC) and consistent Akaike information criterion (CAIC) are calculated to make a comparison among the fitted distributions. Generally, the lesser values of the above-mentioned measures, the better and the most appropriate fit to the information data set. "

5. Conclusion
We proposed and studied a new lifetime cubic transmuted Kappa distribution. The derived model is flexible with variable hazard rate. The Shapes of hazard rate function indicates that the new developed model is a competitive" model for other probability models having "constant, increasing and decreasing failure rate. Moreover, cubic transmuted Kappa distribution has special cases, which style it of divergent statistical significance from other models. We used real data for application purpose. The derived "model is more flexible and give better fit than "well-known existing models. So, we can conclude that our new distribution can be used an alternative models for muddling in various areas. For example, engineering, failure analysis, survival analysis, weather forecasting, extreme value theory, economics (income inequality) and others.
