The present study is an attempt to proposesome improvedexponential type estimators for estimating the population mean precisely under the condition with and without the use of auxiliary information. The large sample properties viz. Biasand MSE forthe proposed estimators have beenobtained and compared with the estimators existing in literature both theoretically as ...

The method of choosing the best boundaries that makes strata internally homogeneous as far as possible is known as optimum stratification. To achieve this, the strata should be constructed in such a way that the strata variances for the characteristic under study be as small as possible. If the frequency distribution of the study variable is known, the stratificati...

In sample surveysgenerallyit is not possible that sample will represent population truly, which results in two types of errors viz. (i) sampling error, and (ii) non-sampling error.Non-response is a type ofnon-sampling error. The present investigation entitled“Some Improved Ratio and Regression Type Estimators in case of Non-Response” has been undertaken with the ob...

An investigation titled “Statistical Models for the Estimation and Projection of Agriculture Share in India’s Gross Domestic Product” was conducted with the objectives: To analyse the Gross Domestic Product of India through time series models and to assess statistically the estimation and projection of agricultural components in Gross Domestic Product. India is an ...

Rice is the main food source for more than half of the world’s population. Basmati rice holds a unique position due to its fragrance, aroma, grain morphology, quality and other desirable traits. India is the world’s leading and exporter of Basmati Rice with an annual production of 60 lakh tonnes, contributing over 70% of the world’s Basmati rice production. In Jamm...

Ordinary least square method (OLS) is an efficient method for estimating the parameters under the presence of assumptions of error term. Moreover, the problems like multicollinearity, auto-correlation, outliers, influential observations, heteroscedasticity etc., do occur and then OLS estimates are less efficient. Under these conditions, different regression techniq...

An investigation entitled on “Statistical Models for Prediction of Height and Diameter Relationships in Chir Pine Trees in Jammu” was conducted on secondary data of 300 Chir Pine trees of Jammu on height and diameter variables (100 trees per forest division i.e Jammu, Nowshera, Batote) from JK forest department, and accordingly data was fitted on eleven height diam...
