根据算术基本定理可知,素数是整数的根基,然而在abc猜想中,根数(radical)也是整数的根基,那么这两种...
Generalized Riemann Hypothesis (2012) 广义黎曼猜想 热度: 相关推荐1 剖析“abc猜想”及“比尔猜想” 王若仲(王洪) 贵州省务川县实验学校 摘要:“abc猜想”最先由英国数学家大卫·马瑟(DavidMasser)及法国数学家乔瑟夫·奥斯达利(Joseph Oesterlé)在1985年独自提出,一直未能被证明。其名字来自把猜想中涉及的三个数...
Northwesterns Gate counts himself among scientists who think amyloid isnt everything, but said nothing has invalidated the amyloid hypothesis. He recently used brain tissue preserved from an old amyloid study to learn how immune cells called microglia can clear those plaques and then switch to ...

P<0.01表示差异性极显著。如果我们是检验某实验(Hypothesis Test)中测得的数据,那么当数据之间具备了显著性差异,实验的虚无假设(Null Hypothesis)就可被推翻,对立假设(Alternative Hypothesis)得到支持;反之若数据之间不具备显著性差异,则实验的备择假设可以被推翻,虚无假设得到支持。
,与H0对立的假设记作H1,称为备择假设(alternative hypothesis) 。⑴ 在原假设为真时,决定放弃原假设,称为第一类错误,其出现的概率通常记作α;⑵ 在原假设不真时,决定不放弃原假设,称为第二类错误,其出现的概率通常记作β (3)α+β 不一定等于1。以上内容参考:百度百科-显著性检验 ...
“Such a hypothesis had the merit of explaining one fact — the discrepancy between thepersonality of Alexander Bonaparte Cust (who could never have made the click with any girl) andthe personality of Betty Barnard’s murderer. And it has been known, before now, that would-bemurderers have ...
