frequencyPerDuration: Frequency Per Duration.

In petersenlab: A Collection of R Functions by the Petersen Lab

Frequency Per Duration.

Description

Estimate frequency of a behavior for a particular duration.

Usage

timesPerInterval(
  num_occurrences = NULL,
  interval = NULL,
  duration = "month",
  not_occurred_past_year = NULL
)

timesPerLifetime(num_occurrences = NULL, never_occurred = NULL)

computeItemFrequencies(
  item_names,
  data,
  duration = "month",
  frequency_vars,
  interval_vars,
  not_in_past_year_vars
)

computeLifetimeFrequencies(
  item_names,
  data,
  frequency_vars,
  never_occurred_vars
)

Arguments

num_occurrences	The number of times the behavior occurred during the specified interval, interval.
interval	The specified interval corresponding to the number of times the behavior occurred, num_occurrences. One of: 1 = average number of times per day 2 = average number of times per week 3 = number of times in the past month 4 = number of times in the past year
duration	The desired duration during which to estimate how many times the behavior occurred: "day" = average number of times per day "week" = average number of times per week "month" = number of times in the past month "year" = number of times in the past year
not_occurred_past_year	Whether or not the behavior did NOT occur in the past year. If 0, the behavior did occur in the past year. If 1, the behavior did not occur in the past year.
never_occurred	Whether or not the behavior has NEVER occurred in the person's lifetime. If 0, the behavior has occurred in the person's lifetime. If 1, the behavior has never occurred in the person's lifetime.
item_names	The names of the questionnaire items.
data	The data object.
frequency_vars	The name(s) of the variables corresponding to the number of occurrences (num_occurrences).
interval_vars	The name(s) of the variables corresponding to the intervals (interval).
not_in_past_year_vars	The name(s) of the variables corresponding to whether the behavior did not occur in the past year (not_occurred_past_year).
never_occurred_vars	The name(s) of the variables corresponding to whether the behavior has never occurred during the person's lifetime (never_occurred).

Details

Estimates the frequency of a given behavior for a particular duration, given a specified number of times it occurred during a specified interval.

Value

The frequency of the behavior for the specified duration.

Examples

timesPerInterval(
  num_occurrences = 2,
  interval = 3,
  duration = "month",
  not_occurred_past_year = 0
)

timesPerInterval(
  duration = "month",
  not_occurred_past_year = 1
)

timesPerLifetime(
  num_occurrences = 2,
  never_occurred = 0
)

timesPerLifetime(
  never_occurred = 1
)
