Check if the given .data is a distribution and normalise it if necessary with an optional laplace correction.
check_distribution(.data, .do.norm = NA, .laplace = 1, .na.val = 0, .warn.zero = F, .warn.sum = T)
.data | Numeric vector of values. |
---|---|
.do.norm | One of the three values - NA, T or F. If NA then check for distrubution (sum(.data) == 1) and normalise if needed with the given laplace correction value. if T then do normalisation and laplace correction. If F then don't do normalisaton and laplace correction. |
.laplace | Value for the laplace correction. |
.na.val | Replace all NAs with this value. |
.warn.zero | if T then the function checks if in the resulted vector (after normalisation) are any zeros, and prints a warning message if there are some. |
.warn.sum | if T then the function checks if the sum of resulted vector (after normalisation) is equal to one, and prints a warning message if not. |
Numeric vector.
