TwoSamplePairedTTest(X1,X2,beta,confidence_option,output_option) Parameters Description • TheTwoSamplePairedTTestfunction computes the paired t-test upon datasetsX1andX2. This means that every entry of the population ofX1is related to an entry of the population ofX2; in the samples,X1[i]is...
The normality assumption is more important for small sample sizes than for larger sample sizes. Normal distributions are symmetric, which means they are equal on both sides of the center. Normal distributions do not have extreme values, or outliers. You can check these two features of a normal...
If the difference between years is small relative to the variation within years, it would take a very large sample size to get a significant two-sample t–test comparing the means of the two years. A paired t–test just looks at the differences, so if the two sets of measurements are ...
Use t7. (Notice that the test is for a single population mean.) Calculate the p-value using the Student’s-t distribution: p-value = 0.0095 Graph: ¯¯¯¯¯XdX¯d is the random variable for the differences. The sample mean and sample standard deviation of the differences are...
One-sample t-tests were used to evaluate preferences compared with 50% (chance, no preference): (1) for the V (vs. NV) hutch and (2) to be together (or separate) in either the V or NV hutch as well as overall. The THI gain inside the V hutch after 1 h with calves present ...
Lineage tracing technology using CRISPR/Cas9 genome editing has enabled simultaneous readouts of gene expressions and lineage barcodes in single cells, which allows for inference of cell lineage and cell types at the whole organism level. While most state-of-the-art methods for lineage reconstruction...

The graph also illustrates a case where the home ranges of two individuals did not overlap, but they shared two positions along a common line (grey circles). Each shared position was counted as a 0.5 m2 overlap Full size image Auto-correlation among data collected for an individual can be ...
To address such concerns, we formu- lated a statistical analysis framework to account for the ran- dom formation of any inter-ligation PETs between two anchors. The null hypothesis assumes that, in the ChIP- enriched chromatin fragment population, each chromatin fragment has an equal chance to ...
