HIMD_R: Scaled SVD Components from Human Internal Migration Database

In bage: Bayesian Estimation and Forecasting of Age-Specific Rates

Scaled SVD Components from Human Internal Migration Database

Description

Objects of class "bage_ssvd" holding scaled SVD components derived from data from the Human Internal Migration Database. HIMD_P1, HIMD_P5, and HIMD_R each hold 5 components

Usage

HIMD_R

HIMD_P1

HIMD_P5

Format

Object of class "bage_ssvd".

Versions:

• "v2024" (default) Data published on 2024-10-23

Details

• HIMD_P1 is derived from data on 1-year migration probabilities, ie the probability that a person will migrate during a time interval of 1 year.

• HIMD_P5 is derived from data on 5-year migration probabilities, ie the probability that a person will migrate during a time interval of 5 years.

• HIMD_R is derived from data on 1-year migration probabilities, using the formula r = -\log(1 - p).
