Econometric Methodology is based on logical positivist principles. Since logical positivism has collapsed, it is necessary to re-think these foundations. We show that positivist methodology has led econometricians to a meaningless search for patterns in the data. An alternative methodology which...

A literature search shows that robust regression techniques are rarely used in applied econometrics. We present a technique based on Rousseeuw and Van Zomeren [Journal of the American Statistical Association, 85 (1990) 633–639] that removes many of the difficulties in applying such techniques...

A central thesis of this paper is that social science is the study of human experience, and hence strongly conditioned by history. Modern Western political, economic and social structures have emerged as a consequence of the repudiation of religion, and are based on secular principles. Many of...

A traditional Islamic education develops an Islamic outlook to life but does not prepare the student assimilate developments over the past three or four centuries, in particular Western knowledge. A modern Western education inevitably entails absorption of a secular worldview built into the...

Current economic theory is mainly concerned with the factors which affect the wealth of nations. Issues of income distribution and elimination of poverty and deprivation are secondary. We suggest an alternative formulation which would make hunger and homelessness, and poverty in general, the...

The Breusch-Pagan Lagrange Multiplier test for heteroskedascity is supposedly able to detect heteroskedasticity which is an arbitrary function of some set of regressors. We will show that in fact it detects only linear functions. The test is inconsistent for general alternatives, in the sense...

The argument that modern economies cannot function without interest is examined in detail. We show that Islamic alternatives to interest, which vary with the context and the type of loan, provide adequate substitutes. Interest based institutions lead to many types of difficulties both practical...

A test can be said to ‘detect’ an alternative hypothesis only if its power against this alternative exceeds its size. We use this principle to define the implicit null and alternative for a test. We analyze the performance of several tests for location and scale parameters. We show that...

Analytic evaluation of heteroskedasticity consistent covariance matrix estimates (HCCME) is difficult because of the complexity of the formulae currently available. We obtain new analytic formulae for the bias of a class of estimators of the covariance matrix of OLS in a standard linear...
