BSTVC V2.Narrower intervals.Three public cases.

The headline V2 result: substantially narrower reported 95% Bayesian credible intervals for temporal and spatial regression coefficients in three public V1/V2 case comparisons. Explore global health-adjusted life expectancy, COVID-19 in China and hepatitis B in the United States.

Weather forecast example: a broad 2–30°C range and a narrow 29–30°C range. — If tomorrow’s forecast is 2–30°C, it’s hard to know what to wear. A range of 29–30°C tells you to dress for heat.

01 / THE COMPARISON

Same case-study data.
Two versions. Two dimensions.

The supplied comparison materials use the same case-study data and matching public analysis settings. They examine 95% Bayesian credible-interval widths for temporal and spatial regression coefficients separately.

Approximate reductions in reported interval widths, V2 compared with V1. Each case and component is summarized by the median of paired interval-width ratios.
Public case study & scope	Outcome type	Temporal width reduction	Spatial width reduction
Global health-adjusted life expectancy177 countries/territories · 2000–2020 12 explanatory variables	Continuous	≈99%	≈38%
COVID-19 in China31 provincial-level units · January–December 2020 6 explanatory variables	Binary	≈94%	≈87%
Hepatitis B in the United States5 Appalachian states · 2012–2023 4 explanatory variables	Count	≈99%	≈98%

The materials report narrower intervals for all 372 temporal comparisons and 96.7% of 2,330 spatial comparisons. In the HALE case, intervals for the 150 countries with shared-border neighbours all narrowed; areas without shared-border neighbours remained broadly similar. Summary percentages are not a common reduction for every interval.

Explore the English comparison frames

The six frames below come directly from the supplied English walkthrough. Orange denotes V1 and blue denotes V2. Select a case to expand its temporal and spatial comparisons; select an image to view it at full size. The percentages summarize each case, rather than every plotted interval.

Global health-adjusted life expectancy Temporal ≈ 99% · Spatial ≈ 38% narrower summaries

HALE temporal comparison: reported case-level interval-width summary approximately 99% narrower in V2; maternal mortality is illustrated. — **Temporal coefficients.** HALE, 2000–2020. Maternal mortality illustrates the comparison; the approximately 99% reduction summarizes the case’s 12 explanatory variables. English walkthrough frame at 01:13.

HALE spatial comparison: approximately 38% narrower case-level summary across 177 countries or territories, with exceptions. Six widest intervals are clipped at the plot boundary. — **Spatial coefficients.** HALE, 177 countries/territories. Maternal mortality is illustrated. The six widest intervals are clipped at the plot boundary; areas without shared-border neighbours are an exception to the narrowing pattern. English walkthrough frame at 01:56.5.

COVID-19 in China Temporal ≈ 94% · Spatial ≈ 87% narrower summaries

COVID-19 temporal comparison: reported case-level interval-width summary approximately 94% narrower in V2; PM2.5 is illustrated. — **Temporal coefficients.** COVID-19 in China, January–December 2020. PM2.5 is illustrated; the approximately 94% reduction summarizes the case’s 6 explanatory variables. English walkthrough frame at 01:21.

COVID-19 spatial comparison: reported case-level interval-width summary approximately 87% narrower in V2 across 31 provincial-level units; PM2.5 is illustrated. — **Spatial coefficients.** COVID-19 in China, 31 provincial-level units. PM2.5 is illustrated; the reported case-level width summary is approximately 87% narrower. English walkthrough frame at 02:03.

Hepatitis B in the United States Temporal ≈ 99% · Spatial ≈ 98% narrower summaries

Hepatitis B temporal comparison: reported case-level interval-width summary approximately 99% narrower in V2; poverty rate is illustrated. — **Temporal coefficients.** Hepatitis B, 2012–2023. Poverty rate is illustrated; the approximately 99% reduction summarizes the case’s 4 explanatory variables. English walkthrough frame at 01:29.

Hepatitis B spatial comparison: reported case-level interval-width summary approximately 98% narrower in V2 across 5 Appalachian states; poverty rate is illustrated. — **Spatial coefficients.** Hepatitis B in 5 Appalachian states. Poverty rate is illustrated; the reported case-level width summary is approximately 98% narrower. English walkthrough frame at 02:09.

00:00The comparison: examine the interval widths reported by V1 and V2 using the same case-study data and matching public analysis settings.
00:20Two key terms: a regression coefficient describes a modelled association. A 95% credible interval is a posterior probability interval conditional on the data and model assumptions; read its width alongside those assumptions and diagnostics.
00:44Three public cases: global health-adjusted life expectancy, COVID-19 in China and hepatitis B in the United States illustrate continuous, binary and count outcomes.
01:00Temporal coefficients: the materials report case-level width summaries approximately 99%, 94% and 99% narrower, respectively.
01:30Temporal summary: the three cases contain 22 explanatory-variable entries and 372 temporal intervals; the materials report that all became narrower.
01:40Spatial coefficients: case-level width summaries were approximately 38%, 87% and 98% narrower. The materials report narrowing for 96.7% of 2,330 spatial intervals; HALE areas without shared-border neighbours remained broadly similar.
02:10Three-case summary: see the table for the temporal and spatial interval-width changes in each case.
