Reporting Error in Age Data of India: A Multivariate Statistical Analysis Approach | Chapter 9 | Recent Trends in Arts and Social Studies Vol. 6

 This branch reported the mistake in age data in India and its reasoning in multivariate statistical approach. Age is an main study variable in demography and epidemiological studies. It is a socio-mathematical variable had connection with the host in descriptive studies and still a commonly assessed risk determinant in analytical studies. It is mainly widely accepted that instruction enhances the accuracy adult reporting. However, an attempt has happened made in the paper to analyse the age reporting mistake in relation to various socioeconomic, cultural, and enlightening factors, in addition to the education factor, in consideration of discover the various singular factors and their plebs in influencing the alternatives in the age reporting error in India.  Ages stated in censuses in developing countries are liable to be subjected errors and bias resulting in doubts in population estimates and age distributions. In order to study this somewhat detailed mathematical analysis, National Family Health Survey (NFHS) data hopeful appropriate in the sense that this is a huge survey top all the states of India on a sample grabbed at random basis. In those reports a measure of age newsgathering error alone for male and female populations has been likely by Myers’ indices. Due to the a lot of variables that may or can not be significant, all variables were subjected to a late regression process at first of the analysis, where any of variables were deleted as they were raise insignificant at the level of significance. The remaining variables were afterward analysed using pleb analysis, which allowed some interesting results. Nonetheless, male literacy gambled a substantial influence in enhancing the feature of age enumerations.  In female part, scheduled family population has some influence on the newsgathering error. Mean household breadth also played few role in doing the age reporting wrong. While studying the pattern between two together periods of time break of about six years, male data in former period of 1992-93 presented illiteracy as the only important factor influencing age newsgathering. Other variables were deleted from late regression process.

Exploring Data Patterns Using Loglinear Analysis | Chapter 8 | Current Strategies in Economics and Management Vol. 3

Consumer needs are diverse and numerous. The FMCG manufacturers are confused due to these diverse consumer needs. This results into brand /product proliferation. The product proliferation happens due to a marketing philosophy of everything for everybody [1] - Choose whatever you need.

This research is an attempt to explore what exactly consumer see while buying a particular bath soapLoglinear Analysis is used here to explore the hidden patterns in the collected data so as to provide the actionable insights for suitable decision making. A situation of Indian bath soap category is undertaken here with reference to understand soap buyer behaviour from urban & rural areas for taking the actionable insights from management perspective.
