Performance of some boundary-seeking mode estimators on the dome bias model

Article Abstract:

Expert estimates may be systematically biased due to several reasons. The dome perspective model offers on example of this phenomenon. Given data with this suspected characteristic, mode estimators which have the capability of producing consensus estimates on the boundary of the convex hull of the sample are needed. Affine linear models are the simplest class of functions with such a capability. The maximum decisional efficiency principle is employed to estimate the parameters of an affine linear group value function.

Big issue for small business

Article Abstract:

Market research is too expensive for most UK companies, but there are affordable ways of obtaining market information. These include employing freelance researchers, purchasing quantitative data, getting in touch with regional development agencies, possibly with a view to joint projects with academic researchers, and contacting Business Links and Training and Enterprise Councils which may have contracts with mutual interest groups and provide market information.

Discriminating between measurement scales using non-nested tests and two-stage least squares estimators: the case of market orientation

Article Abstract:

The market orientation construct created by Narver and Slater, called MKTOR, proved to be better than the one developed by Kohli, Jaworski and Kumar, called MARKOR, in justifying changes in measures of business performance. Evidence also indicates that the outcome from non-nested tests grounded on normal OLS retrogessions and the total measurement of scales may be deceiving.
