Compute the probability that two functions are correlated at a given spherical harmonic degree for a given correlation coefficient.

## Usage

`prob`

= SHConfidence (`l`

, `corr`

)

## Returns

`prob`

: float- Probability that two functions expressed in spherical coefficients with spectral correlation
`corr`

are correlated at degree`l`

.

## Parameters

`l`

: integer- The spherical harmonic degree.
`corr`

: float- The correlation coefficient of the two data sets at degree
`l`

.

## Description

`SHConfidence`

will calculate the probability (between 0 and 1) that two sets of spherical harmonic coefficients with spectral correlation `corr`

are linearly correlated at a given degree. This is calculated using equation A7 from Pauer et al. (2006).
