In lspatial/sptemUS: Constrained Spatiotemporal Mixed-Effect Models for Exposure Estimation of Air Pollutants

Description

Generation of temporal basis function

Usage

getTBasisFun(serDf, idStr, dateStr, valStr, df = 25, n.basis = 2, tbPath = NA)

Arguments

serDf	Time series dataframe, format: (siteid,date,observed value)
idStr	Location id name
dateStr	Date id name
valStr	The target variable's name
df	Degree of freedom
n.basis	Number of temporal basis function
tbPath	The path to save the plots of each temporal basis component. Default: NA, no plots generated

Value

A dataframe of temporal basis function: (date, pvi (the ith temporal basis function output for a date ))
