TextPredictor is a Shiny web app that predicts the next word in a user-entered phrase using unigram, bigram, and trigram frequency tables with a backoff strategy. The system is fast, lightweight, and demonstrates practical applications of R, Shiny, and NLP for text prediction. A 5-slide RPubs presentation explains the model, data, and app functionality.

This project evaluates the financial impact of a workplace wellness programme using data from a randomised control trial (RCT). The analysis begins by cleaning the dataset and renaming variables for clarity. It then explores the data through summary statistics and visualisations, highlighting a potential selection bias where healthier employees are more likely to enrol. To address this, the study contrasts a standard OLS regression, which misleadingly suggests cost savings due to the "healthy user" effect, with an instrumental variables (IV) regression. The IV analysis uses the random assignment of the programme as an instrument to isolate the true causal effect, ultimately revealing that the wellness programme has no statistically significant impact on reducing employee medical spending.

I use simulations to show how the spread of the sample distribution changes with sample size and show that this produces the standard error of the mean.

Kondisi sosial ekonomi di Jawa Timur tahun 2021 mencerminkan perbedaan tingkat kesejahteraan antar kabupaten/kota, yang tercermin dari variasi persentase penduduk miskin, PDB regional, angka harapan hidup, rata-rata lama sekolah, dan pengeluaran per kapita. Beberapa wilayah menunjukkan kapasitas ekonomi dan kualitas hidup yang lebih tinggi, sementara sebagian lainnya masih memerlukan perhatian dalam pengentasan kemiskinan dan peningkatan akses layanan sosial. Metode MDS diterapkan untuk memetakan kedekatan karakteristik sosial ekonomi antar daerah, sehingga hubungan dan kelompok wilayah dengan kondisi serupa dapat diidentifikasi secara visual.
