cohortdeviation {APCI}

Calculate cohort deviation

Description

Calculate cohort deviation

Usage

cohortdeviation(
  A,
  P,
  C,
  model = temp6,
  weight = "wt",
  covariate,
  gee = FALSE,
  unequal_interval = FALSE,
  age_range = NULL,
  period_range = NULL,
  age_interval = NULL,
  period_interval = NULL,
  age_group = NULL,
  period_group = NULL,
  ...
)

Arguments

A, P, C

The numbers of age groups, period groups, and cohort groups separately.

model

A generalized linear regression model generated from the internal function temp_model

weight

An optional vector of sample weights to be used in the model fitting process. If non-NULL, the weights will be used in the first step to estimate the model. Observations with negative weights will be automatically dropped in modeling.

covariate

An optional vector of characters, representing the name(s) of the user-specified covariate(s) to be used in the model. If the variable(s) are not found in data, there will be an error message reminding the users to check the data again.

gee

Logical, indicating if the data is cross-sectional data or longitudinal/panel data. If TRUE, the generalized estimating equation will be used to correct the standard error estimates. The default is FALSE, indicating that the data are cross-sectional.

unequal_interval

Logical, indicating if age and period groups are of the same interval width. The default is set as TRUE.

age_range, period_range

Numeric vector indicating the actual age and period range (e.g., 10 to 59 years old from 2000 to 2019).

age_interval, period_interval, age_group, period_group

Numeric values or character vectors indicating how age and period are grouped. age_interval and period_interval are numbers indicating the width of age and period groups respectively. age_group and period_group are character vectors explicitly listing all potential age and period groups. Either age_interval(period_interval) or age_group (period_group) have to be defined when unequal_interval is TRUE.

...

Additional arguments to be passed to the function.

Value

A list containing:

cohort_average

The estimated inter-cohort average deviations from age and period main effects.

cohort_slope

The estimated intra-cohort life-course linear slopes.

int_matrix

A matrix containing the estimated coefficients for age-by-period interactions.

cohort_index

Indices indicating different cohorts.
