What is distributions3?

distributions3 0.3.0 adds sample-based distributions and likelihood derivatives

An R package giving probability distributions a consistent object interface - d/p/q/r functions, moments, and prodist() methods that pull a fitted distribution out of a regression object. Version 0.3.0 is the first substantive release under Achim Zeileis's maintenance, and it widens what a distribution is allowed to be: Empirical() represents a distribution by a random sample rather than by parameters, and numerical fallbacks now fill in cdf(), pdf(), quantile(), random() and the moments for any object that implements only some of them. New score() and hessian() generics compute first and second derivatives of the log-likelihood with respect to the parameters, analytically for a few distributions and numerically for the rest.

What is PostHog?

PostHog is filling in Logs and the mobile SDKs while quietly growing a support product.

PostHog ships weekly, and this week's batch is spread across four teams rather than concentrated in one product. Logs gets attribute filtering and a React Native capture path; the iOS SDK gains rage-click detection and a session-replay duration floor; Conversations picks up GitHub issues as an inbound support channel. Individually these are small, and the weekly digest bundles them into a single roundup entry.

distributions3 vs PostHog: editorial side-by-side

D6.3

distributions3 0.3.0 adds sample-based distributions and likelihood derivatives

◆ Current state

An R package giving probability distributions a consistent object interface - d/p/q/r functions, moments, and prodist() methods that pull a fitted distribution out of a regression object. Version 0.3.0 is the first substantive release under Achim Zeileis's maintenance, and it widens what a distribution is allowed to be: Empirical() represents a distribution by a random sample rather than by parameters, and numerical fallbacks now fill in cdf(), pdf(), quantile(), random() and the moments for any object that implements only some of them. New score() and hessian() generics compute first and second derivatives of the log-likelihood with respect to the parameters, analytically for a few distributions and numerically for the rest.

◆ Where it's heading

Growth used to arrive as new distribution families contributed from outside - the extreme-value set, Erlang, later the Poisson binomial. This release changes the axis: alongside two new distributions it adds an inference layer (score, hessian) and a forecast-evaluation one (crps() methods against scoringRules), which are capabilities about distributions rather than more of them. Dependency weight is being cut at the same time, with ggplot2 demoted to Suggests and glue replaced by base R sprintf().

◆ Prediction

With numeric fallbacks and the derivative generics in place, expect analytic score() and hessian() methods to be filled in across more of the distribution catalogue. The constructor-default change is the likeliest source of follow-up fixes, since calls like Poisson() now return a length-zero distribution where they previously errored.

PostHog is filling in Logs and the mobile SDKs while quietly growing a support product.

◆ Current state

PostHog ships weekly, and this week's batch is spread across four teams rather than concentrated in one product. Logs gets attribute filtering and a React Native capture path; the iOS SDK gains rage-click detection and a session-replay duration floor; Conversations picks up GitHub issues as an inbound support channel. Individually these are small, and the weekly digest bundles them into a single roundup entry.

◆ Where it's heading

Two build-outs are running in parallel. The observability side — Logs plus the mobile SDKs — is being brought up to parity with what PostHog already offers on web, which is what makes the platform credible for mobile teams rather than web analytics with an SDK attached. The Conversations work is the more interesting thread: adding support channels moves PostHog past measuring users toward handling them, and it is being built out in the same incremental weekly rhythm as everything else.

◆ Prediction

Expect Logs and the mobile SDKs to keep receiving parity features on the weekly cadence, and expect Conversations to add further inbound channels beyond GitHub issues. The entries do not show whether Conversations is being positioned as a standalone product or a feature of the existing suite.
