Restricted maximum likelihood estimation under Eisenhart model Ill

For a balanced two-way mixed model, the maximum likelihood (ML) and restricted ML (REML) estimators of the variance components were obtained and compared under the non-negativity requirements of the variance components by L ee and K apadia (1984). In this note, for a mixed (random blocks) incomplete block model, explicit forms for the REML estimators of variance components are obtained. They are always non-negative and have smaller mean squared error (MSE) than the analysis of variance (AOV) estimators. The asymptotic sampling variances of the maximum likelihood (ML) estimators and the REML estimators are compared and the balanced incomplete block design (BIBD) is considered as a special case. The ML estimators are shown to have smaller asymptotic variances than the REML estimators, but a numerical result in the randomized complete block design (RCBD) demonstrated that the performances of the REML and ML estimators are not much different in the MSE sense.

Cost-efficacy analysis of biological treatments in psoriasis: an 18-month assessment

Summary

This study compared the cost-efficacy of the following approved biological treatment strategies for plaque psoriasis over 18 months: (1) alefacept 15 mg intramuscularly weekly for two 12-week courses; (2) efalizumab 1 mg/kg subcutaneously (SC) weekly; and (3) etanercept 50 mg SC twice weekly for 12 weeks followed by a maintenance dose of 50 mg weekly. Direct utilisation-related costs included drug costs, office fees, injection fees and costs incurred due to adverse events and laboratory monitoring. Efficacy was based on response rates from large-scale clinical trials. At 18 months, total utilisation-related costs for alefacept, efalizumab and etanercept were $26,667, $33,365 and $32,962, respectively. Cost-efficacy, calculated using the corresponding response rates for the three therapies, was comparable ($66,669, $75,828 and $61,041, respectively). Thus, for patients with moderate to severe psoriasis who have responded to therapy, two 12-week courses of alefacept 7 months apart, or weekly maintenance treatment with efalizumab or etanercept, resulted in comparable total cost-efficacy.     

发达国家中小企业税收政策对我国的启示

发达国家非常重视中小企业,采取种种税收鼓励措施扶持其发展。我国没有建立起规范的中小企业税收制度,政策优惠力度不足,增值税制不完善,需要进一步建立与完善有利于中小企业发展的税收政策体系,提高税法级次,调整现行政策,加大对中小企业的税收支持力度,促进中小企业的快速发展。
