Noise is integral in the software failure data. A conversion of data is needed to smooth out the noise. Smoothing
enhances quality at first as the size increments and turns out to be more regrettable as the gathering size is vast. Order statistics
deals with applications of ordered random variables and functions of these variables. When failures are frequent or inter failure
time is less, the use of order statistics is significant. Classical Hypothesis testing needs more time to draw conclusions by collecting
volumes of data. But, to decide upon the reliability or unreliability of the developed software very quickly Sequential Analysis of
Statistical science could be adopted. The method embraced for this is, Sequential Probability Ratio Test (SPRT), which is designed
for continuous monitoring. The likelihood based SPRT proposed by Wald is very general and it can be used for many different
probability distributions. The method used to derive the unknown parameters is Maximum Likelihood Estimation (MLE). In this
paper, a control mechanism based on Order statistics and Sequential Probability Ratio Test is applied using mean value function of
Rayleigh distribution and analysed the results.

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
