The current work assessed some of the key hypotheses behind the generation of the pattern electroretinogram (PERG) response. The first of these hypotheses states that the PERG response is the result of linear cancellation of simultaneous increment and decrement retinal responses, as generated by the retinal ON- and OFF-pathways. Experiment 1 evaluated the possibility of simulating the PERG by summing the ERG responses elicited by increment and decrement flashes, and found that it was indeed possible to simulate the PERG from these responses. However, only the steady-state PERG could be modeled consistently. The second hypothesis evaluated a theory that the …

In many studies, the measurement of sampling units according to the response variable is costly or time consuming, however, it is possible to rank sampling units according to baseline auxiliary covariates, which are available, easily obtainable, and cost efficient. In these cases, when estimating the population mean, Ranked Set Sampling (RSS) can be a more efficient sampling method than the Simple Random Sampling (SRS) method. In this dissertation, we propose a modified approach of the RSS method to allocate units into an experimental study, aimed to compare two or more groups.
Ranked auxiliary covariates, which are typically correlated with the …
