Function to Impute Values When Qualifier Exists in Character Result

Derive an imputed value

Usage

compute_qual_imputation(character_value, imputation_type = 1, factor = 0)

Arguments

character_value

Character version of value to be imputed

imputation_type

(default value=1) Valid Values: 1: Strip <, >, = and convert to numeric. 2: imputation_type=1 and if the character value contains a < or >, the number of of decimals associated with the character value is found and then a factor of 1/10^(number of decimals + 1) will be added/subtracted from the numeric value. If no decimals exists, a factor of 1/10 will be added/subtracted from the value.

factor

Numeric value (default=0), when using imputation_type = 1, this value can be added or subtracted when the qualifier is removed.

Value

The imputed value
