Comment: Understanding OR, PS and DR

We congratulate Kang and Schafer (KS) on their excellent article comparing various estimators of a population mean in the presence of missing data, and thank the Editor for organizing the discussion. In this communication, we systematically examine the propensity score (PS) and the outcome regression (OR) approaches and doubly robust (DR) estimation, which are all discussed by KS. The aim is to...

Comment on the comment by Dr. Marino and Dr. Frilot on "Proposed test for detection of nonlinear response in biological preparations exposed to RF energy".

In their Comment on the paper of Balzano [2002] on the detection of nonlinear responses, Marino and Frilot [2003] state that certain possible biological systems with a response described by ‘‘non linear differential equations’’ can respond (chaotically) to an interaction that is ‘‘arbitrarily small, say kT/10.’’ This is correct but does not lead to the conclusion that significant biological eff...

Spatial resolution and gain control are important sensory-system functions that frequently involve lateral inhibition, which can increase spatial tuning of a neuron by effectively reducing the area of its receptive-field center. In the vertebrate retina, lateral inhibition can modulate the direct pathway for light-evoked signals (photoreceptors to bipolar cells to ganglion cells) both via horiz...
