Fig. 2: Persistence coefficients plots for De Bilt.
From: Increased persistence of warm and wet winter weather in recent decades in north-western Europe

Persistence coefficients plots obtained by fitting Model (1) to data for De Bilt. Shaded areas represent 95% pointwise confidence bounds. a ϕt(τ) for τ ∈ {0.1, . . . , 0.9} fitted on the “new” data. b ϕt(0.05) fitted on “old” and “new” data. c ϕt(0.5) fitted on “old” and “new” data. d ϕt(0.95) fitted on “old” and “new” data.
