Briefly define the distribution of sample means. Distributions: Distributions in statistics are merely a way that all the data in a set is represented in some form. Distributions can provide information about the data set, such as how often certain values occur, how variable the values are, and...

Is the below statement true or false? Explain. A truly random series will likely have a very small number of runs. Identify or define the term: F c r i t Define the sample covariance, \hat{C} ( \left \{ Y_i \right \}_{i = 1}^{n} ) mathematically and explain what it me...

Historically, breast tumor subtype assignments were calculated from bulk-RNA-seq data using published methods for the PAM50 assay51; however, assigning tumor subtypes from gene expression is confounded by the composition of tumor and non-tumor cells in a sample. To disentangle subtype assignment from...
