Ratio of standard deviations between `sim`

and `obs`

, with treatment of missing values.

`sim` |
numeric, zoo, matrix or data.frame with simulated values |

`obs` |
numeric, zoo, matrix or data.frame with observed values |

`na.rm` |
a logical value indicating whether 'NA' should be stripped before the computation proceeds. |

`...` |

Ratio of standard deviations between `sim`

and `obs`

.

If `sim`

and `obs`

are matrixes, the returned value is a vector, with the ratio of standard deviations between each column of `sim`

and `obs`

.

`obs`

and `sim`

has to have the same length/dimension

The missing values in `obs`

and `sim`

are removed before the computation proceeds, and only those positions with non-missing values in `obs`

and `sim`

are considered in the computation
