Main Outcome Measure: Independent statistical analyses (analysis of variance, p <.05) were conducted on logged coefficients of variation and logged means data to investigate for repeatability and for size differences, respectively.
The log-normal mean and log-normal coefficient of variation and 95% confidence intervals (CIs) (including the lower and upper confidence limits) for total variance were calculated using the linear mixed effect model with site and day/run, and within-run as random effects.
As shown in Table 2, " r " for a simple linear regression between log D Sr and log R is 0.667, which means that 66.7% of variation in log D Sr values is caused by log R.
These criteria provide a simple approach to classify cerebellar units using only a few statistical parameters describing the firing frequency and irregularity of discharge: the mean spike frequency (MSF), the coefficient of variation of the log of the ISI (LCV), and entropy of the ISIs (ENT).
Our key strategies include the use of base-level log-ratios to remove GC-content bias, correction for an imbalanced library size effect on log-ratios, and the estimation of log-ratio variations via binning and interpolation.
This assumption may not hold so, as a sensitivity analysis, we estimate a standard Cobb Douglas production function to examine variations in the log of hospital output (both cost and quality adjusted).
The relative duplicate error was used to assess test-retest reproducibility of the PD100Rint, EI (assuming a normal distribution), defined as a standard deviation of the differences divided by the v2 after log transformation (approximates coefficient of variation)[ 18].
The first major result of our analysis is to note that in many individual embryos the nucleus to nucleus variation in the log of concentration is independent of spatial position.
The EGFP and EYFP fluorescence distributions in the clone were unimodal and qualitatively log-normal with coefficients of variation (CV = standard deviation/mean) of between 0.5 and 0.7 (depending on the day of measurement), and signals spanning at least an order of magnitude (Fig. 1B, main panel).
There was the story and choreography of the billy goat in the well, the parable of the three frogs on a log, variations on his theme of shake it off, stamp it down, rise above it.
However, since T2* is not normally distributed, we will report T2* as the geometric mean (antilog of the mean of the log data) and per cent coefficient of variation (CV equivalent to the variance of the mean in log scale) following log transformation of data.
