(TCESS) was calculated for each TF adapting a previously entropy-based approach to single-cell RNA-seq data75(see Supplementary Table10within the Supplementary Data file). Briefly, given a cluster C, which had n cells, the total expression of TFawas calculated using the following formula (Eq...
(when fitted to diameter) the exponent is close to 3. Although there is some scatter, the weight of the measured data suggests a strong tendency towardVnuc∝rnuc3∝N. If we use the formula for radius fromEq. (1)(i.e.,rnuc=bξN/2) to calculate the volume of an ideal sphere we ...
For the second and third periods, the criterion formula has been updated by splitting the data into two time periods: before and after the fence installation. Thus, the criterion (CW23) corresponds to the sum of squared of differences per time window (k), zones (z) and fencing periods (...
How do we calculate the null hypothesis using t-test for this data? Is there a formula? Also how can we determine the significant level? Group Statistics |Sex|N|MEan|Std. Deviation|Std. Error Mean |T How do you interpret statistical da...
I derive the exact distribution of the unpaired t-statistic computed when the data actually come from a paired design. I use this to prove a result Diehr et al. obtained by simulation, namely that the type I error rate of this procedure is no greater than regardless of the sample size. ...
The formula is provided in Equation 1: ⎛ c A ⎞⎛ 2N −c A ⎞ Pr(I A,B | N,cA,cB) = ⎝⎜⎜ I A,B ⎠⎟⎟⎝⎜⎜ c B − I ⎛ 2N ⎞ A,B ⎠⎟⎟ ⎜ ⎝ cB ⎟ ⎠ (1) Li et al. Genome Biology 2010, 11:R22 http://genomebiology...
When the CN data were used for analysis of classification accuracy of the methods, the ECD set provides the highest, closely followed by the standard Wilcoxon sign ranked test, EDGE and the t-test. While none of 2,829 probe sets from the ECD had 2 or more misclassified sample pairs, the...
(YI) was used to calculate the best cut-off value of the abovementioned 5 miRNAs for early diagnosis of NSCLC. The formula is YI = sensitivity + specificity − 1. When the YI is highest, the relative level of miRNA is the best cut-off value. The results are showed as...
