normal , the ICC refers neither to any natural parameter of a data generating model nor to any function of its parameters. For this reason we do not offer the user a option to input the variance between the clusters.

If you prefer to use that input, we suggest using the cps. binary function. This function was inspired by work from Stephane Champely pwr. test and Peter Dalgaard power. As with those functions, 'uniroot' is used to solve power equation for unknowns, so you may see errors from it, notably about inability to bracket the root when invalid arguments are given. This generally means that no solution exists for which the omitted parameter and the supplied parameters fulfill the equation. In particular, the desired power may not be achievable with any number of subjects or clusters.

A binary option is a financial product where the parties involved in the transaction are assigned one of two outcomes based on whether the option expires in the money. Binary options depend on the outcome of a "yes or no" proposition, hence the name "binary.

A binary option automatically exercises , meaning the gain or loss on the trade is automatically credited or debited to the trader's account when the option expires.

That means the buyer of a binary option will either receive a payout or lose their entire investment in the trade—there is nothing in between. Conversely, the seller of the option will either retain the buyer's premium , or be required to make the full payout. The trader makes a decision, either yes it will be higher or no it will be lower. A vanilla American option gives the holder the right to buy or sell an underlying asset at a specified price on or before the expiration date of the option.

A European option is the same, except traders can only exercise that right on the expiration date. Vanilla options, or just options, provide the buyer with potential ownership of the underlying asset.

Binary options differ in that they don't provide the possibility of taking a position in the underlying asset. Binary options typically specify a fixed maximum payout, while the maximum risk is limited to the amount invested in the option.

Movement in the underlying asset doesn't impact the payout received or loss incurred. The profit or loss depends on whether the price of the underlying is on the correct side of the strike price. Some binary options can be closed before expiration, although this typically reduces the payout received if the option is in the money.
