  • Quantiles based Neighborhood Method of Classification 
    Sampath, S.; Suresh, S. (2019-05-01)
    Classification of objects is an important problem that has received the attention of several researchers in Data Mining. Necessity for classification of an object into one of the predefined classes arises in several domains ...
  • Statistical Issues in Small and Large Sample: Need of Optimum Upper Bound for the Sample Size 
    Chandrasekharan, Subramanian; Sreedharan, Jayadevan; Gopakumar, Aji (2019-11-01)
    As fewer samples are meaningless and lead to fallacious conclusions, researchers are used to calculate minimum sample size before the conduct of any study. Although the larger samples can yield more accurate results, an ...

    Al-Saleh, Mohammad Fraiwan (2019-11-01)
    In this paper, several Educational Statistical Tools for summarizing a test marks are discussed. The mean, variance, 5- number summary, Difficulty index and Discrimination index are discussed in details. The tools are ...
  • Time Control Chart – Log Logistic Distribution 
    B., SriRam; A., Suhasini; R.R.L., Kantam (2019-05-01)
    The time to failure of a product is considered as a quality characteristic of following Log-Logistic distribution (β = 3). Control limits are evaluated for the time to failure. Life time data are compared with the control ...
  • Using Rank of the Auxiliary Variable in Estimating Variance of the Stratified Sample Mean 
    Shabbir, Javid; Gupta, Sat (2019-11-01)
    We propose a generalized class of estimators for finite population variance using the auxiliary variable as well as rank of the auxiliary variable in stratified sampling. We identify many estimators as special cases of ...
