摘要:

Two full information estimators and a limited information estimator for the simultaneous equation model with autocorrelated errors are studies by the Monte Carlo method.The estimators share features of the two-step Gauss-Newton procedure and of Aitken generalized least squares.One full information method generates the estimated endogenous variables used in the later stages of computation from the unrestricted reduced form while the other uses a restricted reduced form.The observed small sample behavior was close to that suggested by asymptotic theory.

摘要:

Linea0r combinations of B-spline coefficients which provide statistically meaningful hypothesis tests are identified. These tests include the importance of breakpoints, continuity constraints, and higher order terms.The important linear combinations turn out to be contrasts whose coefficients are determined by differencing the left- and right-hand limits of the B-splines or their derivatives at certain knots. A FORTRAN program for testing single degree of freedom hypotheses is discussed.

摘要:

A simulation of regressions is used to generate estimates by iteration of the generalized ridge parameter.The simulation results indicate that generalized ridge parameters estimated by iteration from near collinear data may be quite different from unknown optimal values.

摘要:

The statistical properties of quasi-ranges in small samples from a gamma density are the objects of study in this paper.The methods of computing the "Coefficient MatrixnA(j,k), which plays a major role for computing moments and quantiles from such a density using high speed digital computers, are presented. Limited tables of central and non-central moments as well as tables of quantile values, are given. More extensive tables can be easily constructed by using the methods described here when the need arises. Also, a table of values for kurtosis and skewness is presented.

摘要:

This article is concerned with modifications of both maximum likelihood and moment estimators for parameters of the three-parameter gamma distribution. Modifications employed here are essentially the same as those previously considered by the authors (1980, 1981) in connection with the lognormal distribution. Sampling behavior of the estimates is indicated by a Monte Carlo simulation. For certain combinations of parameter values, these new estimators appear better than both maximum likelihood and moment estimators with respect to bias, variance and/or ease of calculation.

摘要:

The exact null distribution of Wilks' LVC_ criterion for testing the hypothesis, α and ρ unknown,against the alternative A ≠ H where, in a p-variate complex normal population, has been derived in a gamma series form and in an alternate series form using contour integration. Percentage points for p =2 (1) 8 for various levels of significance and various degrees of freedom have been computed but in this paper we present selected tables only.
