  "Description": "Fits time-varying effect models (TVEM). These are a kind\nof application of varying-coefficient models in the context of\nlongitudinal data, allowing the strength of linear, logistic,\nor Poisson regression relationships to change over time.  These\nmodels are described further in Tan, Shiyko, Li, Li & Dierker\n(2012) <doi:10.1037/a0025814>.  We thank Kaylee Litson,\nPatricia Berglund, Yajnaseni Chakraborti, and Hanjoo Kim for\ntheir valuable help with testing the package and the\ndocumentation.
