source : IEnumerable<'TSource> *
selector : Func<'TSource, Nullable<decimal>> -> Nullable<decimal>
Parameters
- source
- Type: System.Collections.Generic.IEnumerable<TSource>
A sequence of values to calculate the population standard deviation of. - selector
- Type: System.Func<TSource, Nullable<Decimal>>
A transform function to apply to each element.
