Implements novel accuracy-level metrics for evaluating continuous
    data prediction models. Four metrics are provided: Counted Squared Error
    (CSE), Counted Absolute Error (CAE), Counted Absolute Percentage Error
    (CAPE), and Symmetric Counted Absolute Percentage Error (SCAPE). These
    metrics offer robust, consistent, and interpretable evaluation on a 0-100%
    scale, addressing limitations of conventional metrics like RMSE, MAE, and
    MAPE. The package integrates with 'caret', 'tidymodels', and common
    forecasting frameworks. Based on Agustini, Fithriasari, and Prastyo (2026)
    <doi:10.1016/j.dajour.2025.100661>.

Interact with the Attentional Control Data Collection (ACDC) or the Truth Effect Database (TED).
  Download the databases using download_acdc() or download_ted(), connect to the database via connect_to_db(), set filter arguments via add_argument()
  and query the database via query_db().

The functions are designed to calculate the most widely-used county-level variables in 
  agricultural production or agricultural-climatic and weather analyses. To operate some functions 
  in this package needs download of the bulk PRISM raster. See the examples, testing versions and 
  more details from: <https://github.com/ysd2004/acdcR>.

Provides tools for autoregressive conditional duration (ACD, Engle and Russell, 1998) models. Functions to create trade, price, or volume durations from transaction data, perform diurnal adjustments, fit various ACD models, and test them.

A function for estimating factor models. Give factor-adjusted statistics, 
  factor-adjusted mean estimation (one-sample test) or factor-adjusted mean difference 
  estimation (two-sample test).

The ACE file format is used in genomics to store contigs from sequencing machines.
  This tools converts it into FASTQ format. Both formats contain the 
  sequence characters and their
  corresponding quality information. Unlike the FASTQ file, the ace file stores the
  quality values numerically.
  The conversion algorithm uses the standard Sanger formula. The package facilitates insertion
  into pipelines, and content inspection.
