Assuming that Yns = 0 if s ≤ 0, because our sample starts on January 19, and no laboratory confirmed case was reported before January 19 in cities outside Wuhan. Xnt=x1t′⋯xnt′′ is an n × k matrix of the control variables. Hnt,s(αwithin) is an n × n diagonal matrix corresponding to the s-day time lag, with parameters αwithin={αwithin,τk}k=1,⋯,Kwithin,τ=1,2. For example, for s = 1,⋯ , 7, the i th diagonal element of Hnt,s(αwithin) is 17∑k=1Kwithinαwithin,1kh¯ct,ik1, and for s = 8,⋯ , 14, the i th diagonal element of Hnt,s(αwithin) is 17∑k=1Kwithinαwithin,2kh¯ct,ik2. Mnt,s(αbetween) is constructed similarly. For example, for s = 1,⋯ , 7 and i≠j, the ij th element of Mnt,s(αbetween) is 17∑k=1Kbetweenαbetween,1km¯ijtk1. Zntτ is an n × KWuhan matrix corresponding to the transmission from Wuhan. For example, the ik th element of Znt1 is m¯i,Wuhan,tk1z¯t1.","tracks":[{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T189","span":{"begin":60,"end":63},"obj":"Disease"}],"attributes":[{"id":"A189","pred":"mondo_id","subj":"T189","obj":"http://purl.obolibrary.org/obo/MONDO_0007921"},{"subj":"T189","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T372","span":{"begin":343,"end":346},"obj":"http://purl.obolibrary.org/obo/CLO_0050236"},{"id":"T373","span":{"begin":384,"end":387},"obj":"http://purl.obolibrary.org/obo/CLO_0007052"},{"id":"T374","span":{"begin":422,"end":427},"obj":"http://purl.obolibrary.org/obo/CLO_0050050"},{"id":"T375","span":{"begin":676,"end":681},"obj":"http://purl.obolibrary.org/obo/CLO_0050050"}],"attributes":[{"subj":"T372","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T373","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T374","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T375","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T873","span":{"begin":0,"end":45},"obj":"Sentence"},{"id":"T874","span":{"begin":46,"end":207},"obj":"Sentence"},{"id":"T875","span":{"begin":208,"end":267},"obj":"Sentence"},{"id":"T876","span":{"begin":268,"end":404},"obj":"Sentence"},{"id":"T877","span":{"begin":405,"end":616},"obj":"Sentence"},{"id":"T878","span":{"begin":617,"end":658},"obj":"Sentence"},{"id":"T879","span":{"begin":659,"end":770},"obj":"Sentence"},{"id":"T880","span":{"begin":771,"end":845},"obj":"Sentence"},{"id":"T881","span":{"begin":846,"end":906},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T873","pred":"source","obj":"LitCovid-sentences"},{"subj":"T874","pred":"source","obj":"LitCovid-sentences"},{"subj":"T875","pred":"source","obj":"LitCovid-sentences"},{"subj":"T876","pred":"source","obj":"LitCovid-sentences"},{"subj":"T877","pred":"source","obj":"LitCovid-sentences"},{"subj":"T878","pred":"source","obj":"LitCovid-sentences"},{"subj":"T879","pred":"source","obj":"LitCovid-sentences"},{"subj":"T880","pred":"source","obj":"LitCovid-sentences"},{"subj":"T881","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PD-MONDO","color":"#ec93e2","default":true},{"id":"LitCovid-PD-CLO","color":"#93ecdc"},{"id":"LitCovid-sentences","color":"#ecc293"}]}]}}
