Currently, TypeScript definitions does not include Kendo RecurrenceEditor widget. It is not officially documented (hence typescript definitions are missing), as it is designed for Scheduler usage only and more specficially for the built-in event editor (it cannot be posted and etc).
For the time being, you will need to add the RecurrenceEditor TypeScript definitions manually to the kendo.all.d.ts file.
I will log this request in our product backlog item for future implementation.
