How to clear ng-select selection

Is it possible to programmatically clear the selection of an ng-select dropdown? I'm wanting the equivalent behaviour of clicking the clear icon, but triggered programmatically.

I was expecting a clear() method or something similar, but the documented API doesn't have anything along those lines.

This is my dropdown code:

<ng-select class="ng-select-wrap"
           [searchFn]="multiTermSearch"
           [items]="calculationOptions"
           placeholder="Please select..."
           name="calculation"
           #calculationValue="ngModel"
           [(ngModel)]="selectedCalculation">
</ng-select>

Here is solution from comment:

  // Access ng-select
  @ViewChild(NgSelectComponent) ngSelectComponent: NgSelectComponent;

  // Call to clear
  this.ngSelectComponent.handleClearClick();

Note that handleClearClick isn't exposed in docs as public api method however as Tim mentioned it's public method so it's possible to call it.
