or fully influencing the current observation. After merger, few series are not
recorded due to discontinuation of series because of many reasons like
inadequate performance, new technology changes, increasing market
operation etc. This is dealt by various econometrician and policy makers and
termed merger. Since few decades it’s becoming very popular to handle the
problem of weaker organization to improve its functioning or acquire it to help
the employees as well as continue the ongoing business. Therefore, a model
is proposed in time series to classify the merger and acquire scenario in
modeling. A classical and Bayesian inference is obtained for estimation and its
confidence interval. Various testing methods are also used to observe the
presence of merger series in the acquire series. Simulation study is verifying
the use and purpose of model. Recently, SBI associate banks are merged in
SBI to strengthen the Indian Banking. Thus, mobile banking data of these
banks was used to analysis the empirical presentation of the model and
recorded that merger has a significant effect for the SBI series in terms of
reducing the transactions.
