DOI: 10.1002/jbio.202100340
Abstract: Optical coherence tomography angiography (OCTA) can map microvascular networks and quantify blood flow velocities with high resolution by calculating intensity standard deviations of time-series signals. However, statistical calculations of the standard deviations need much processing… read more here.

Are Cramér‐Rao lower bounds an accurate estimate for standard deviations in in vivo magnetic resonance spectroscopy?

DOI: 10.1002/nbm.4521
Abstract: Due to inherent time constraints for in vivo experiments, it is infeasible to repeat multiple MRS scans to estimate standard deviations on the desired measured parameters. As such, the Cramér‐Rao lower bounds (CRLBs) have become… read more here.

DOI: 10.1038/s41433-022-01961-3
Abstract: We provide global averages and standard deviations for ocular biometry—axial length (AL), corneal radius of curvature (CR), anterior chamber depth (ACD), lens thickness (LT), white to white (WTW), and central corneal thickness (CT). We hope… read more here.

DOI: 10.1038/s41598-018-36722-4
Abstract: High throughput screening (HTS) assesses compound libraries for “activity” using target assays. A subset of HTS data contains a large number of sample measurements replicated a small number of times providing an opportunity to introduce… read more here.

DOI: 10.1111/ele.14144
Abstract: The log response ratio, lnRR, is the most frequently used effect size statistic for meta-analysis in ecology. However, often missing standard deviations (SDs) prevent estimation of the sampling variance of lnRR. We propose new methods… read more here.

DOI: 10.18187/pjsor.v13i4.1834
Abstract: In stratified sampling design when the cost of measuring the units is not significant in each stratum, the estimation of population mean or total constructed from a selected sample according to Neyman allocation is advisable.… read more here.

What Does It “Mean”? A Review of Interpreting and Calculating Different Types of Means and Standard Deviations
Sign Up to like & getrecommendations! Published in 2017 at "Pharmaceutics"
DOI: 10.3390/pharmaceutics9020014
Abstract: Typically, investigations are conducted with the goal of generating inferences about a population (humans or animal). Since it is not feasible to evaluate the entire population, the study is conducted using a randomly selected subset… read more here.
