timesPerInterval: 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
)

Value

The frequency of the behavior for the specified duration.

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.

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
)
