Robust interquantile multilayer perceptron 1.0.
Internal code: Interquantile 1.0 ; 2020
Technical parameters: Kód v Pythonu je samostatně spustitelný. Je třeba, aby uživatel instaloval v Pythonu math, NumPy, TensorFlow a Keras. Spuštění kódu je přímočaré podle dokumentace. Dostupné pod licencí MIT.
Economic parameters: Software umožňuje uživateli provést robustní trénování neuronových sítí založené na vhodných (spolehlivých) pozorováních mezi dvěma nelineárními regresními kvantily. Kód je implementován velmi efektivně a přehledně. Práce s kódem je tak výpočetně rychlejší oproti jiným implementacím, které využívají komplikované a tedy zdlouhavé postupy.

Heteroscedastic multicollinear regression 1.0.
Internal code: Heter 1.0 ; 2020
Technical parameters: Kód v softwaru R je samostatně spustitelný podle dokumentace, která je součástí jednotlivých souborů. Spuštění vyžaduje knihovny glmnet, quantreg, Qtools. Dostupné pod licencí MIT.
Economic parameters: Soubory prezentují vzorovou regresní analýzu za nestandardních podmínek (za heteroskeasticity a zároveň multikolinearity). Jednotlivé příkazy jsou v zásadě známé, ale přínos softwaru je v tom, že sofistikovaně využívá široké spektrum rozličných nástrojů (regresní odhady, testy hypotéz, odhady kvantilů), jejichž vyhledávání by jinak bylo pro uživatele časově náročné.
