## Analyzes genes versus BestKeeper index

### Description

All genes are combined into an index. Then, correlation between each genes and the index is calculated, describing the relation between the index and the contributing gene by the Pearson correlation coefficient (r), coefficient of determination (r2) and the p-value.

### Usage

```
bki(expression, ctVal = TRUE)
```

### Arguments

`expression` |
a matrix of expression levels. Each row corresponds to a sample and each column to a gene. |

`ctVal` |
a logical value indicating data type. If ct-values are input, ctVal=TRUE, otherwise, ctVal=FALSE. |

### Value

A matrix of the Pearson correlation coefficient (r), coefficient of determination (r2) and the p-value.
