To allow for easier comparisons between genes, especially for the combined expression plots, the mean difference in expression, hereafter referred to as ‘mean difference’, of the sample grouping to all other (parietal and frontal) sample groupings were calculated and plotted. This allows the ...
logarithmic mean:对数平均数 x−ylnx−lny ,其中 x≠y ,可以通过微分中值定理 (Mean Value Theorem of Differential Calculus) 推广到任意 n 个数。 In words: the difference of two numbers divided by the difference of their logarithms. ...
This study focuses on re-examining the early 2000s hiatus and the associated key components of the global mean surface temperature (GMST) using multiscale statistics for five well-known gridded surface temperature and two reanalysis datasets. The hiatus is characterized as a near-zero trend on ...

H1: There is at least one mean difference among the populations. 第四,analysis of variance In everyday language, the scores are different; in statistical terms, the scores are variable. Our goal is to measure the amount of variability (the size of the differences ) and to explain why the...
of a least squares line may not be interesting from a statistical standpoint, there is one point that is. Every least squares line passes through the middle point of the data. This middle point has anxcoordinate that is themeanof thexvalues and aycoordinate that is the mean of theyvalues....
a. What does "least-squares estimates" mean? What is being estimated? What is being squared? In what sense are the squares "least"? R2 R2 Coefficient of Determination: The coefficient of determination shows the relationship between explanatory and ex...
