Abstract

For one reason or the other, in the regression analysis of cross-section data in general and of consumer-budget data in particular, one has to deal with grouped observations rather than the original ungrouped observations. In other words, this means that the original observations are first grouped into an appropriate number of classes formed on the basis of some desirable criterion, then class means are obtained for the variables—explained as well as explanatory-entering the regression model, and the regression analysis is applied to these class means.

Abstract

In the context of planned development in India, the reliability of forecast of private bill of goods which constitutes a major share of total final bill of goods (including public demand) is important, for in the planning models which seem to have been used in India the reliability of plan targets of gross output of various sectors depends largely, inter alia, on how precise the estimate of private final demand vector is. Available evidence shows that this final demand vector is built, among others, on the assumption of inter-regional homogeneity of consumer behaviour in India.

Abstract

In the present paper an attempt has been made to answer the following important questiong:

(a) Are input-output coefficients invariant over the regions?

(b) Are input-output coefficients invariant over time?

(c) Is there 'size of sector' effect on input-output coefficients?

Alternatively, in statistical parlance, the object of our analysis is to test the following three null hypotheses corresponding to (a), (b) and (c) respectively:

(i) There is no regional effect on input-output coefficients.

(ii) There is no temporal effect on input-output coefficients.

(iii) There is no 'size of sector' effect on input-output coefficients.

Abstract

In Engel curve analysis, it is not uncommon to obtain regression of mean consumption on mean income (usually total expenditure) instead of corresponding variables or their appropriate transformations for individual households. This approach is followed because micro-level individual households data are either not available or even when available cost involved in processing these is too high to warrant their use in Engel curve analysis.

Abstract

At present, of the various contraceptive techniques that are available, only two, namely vasectomy or sterilization operation of the male, and IUCD, satisfy all the following desirable criteria: (i) They are almost cent per cent effective, (ii) They are independent of patient's reliability-the most vital factor among the people with weak motivation, who have merely the desire but not the will to limit the size of their family.
