WebThe Fischer indole synthesis is one of the oldest and most effective methods of indole development and was first invented by Fischer in 1883. A variety of indole may be prepared from aryl hydrazines and substituted ketones or aldehydes in the presence of Brønsted or Lewis acids. The most useful route to indoles is the Fischer indole synthesis ... Scoring algorithm, also known as Fisher's scoring, is a form of Newton's method used in statistics to solve maximum likelihood equations numerically, named after Ronald Fisher.
WebThe Fischer indole synthesis offers a straightforward approach to construct the indolo [2,3-a ]quinolizine ring system. This method was popular in 1950s and a number of indolo [2,3- a ]quinolizidine derivatives were prepared 〈50MI 837-01, 50JCS1534, 52JA4960, 57JA3770, 58JCS2024, 58JCS2038, 58JOC435, 63JCS3440, 67CPB499, 73IJC621〉. In statistics, Fisher's method, also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald Fisher. In its basic form, it is used to combine the results from several independence tests bearing upon the same … See more Fisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula $${\displaystyle X_{2k}^{2}\sim -2\sum _{i=1}^{k}\log(p_{i}),}$$ where pi is the p … See more In cases where the tests are not independent, the null distribution of X is more complicated. A common strategy is to approximate the null distribution with a scaled See more A closely related approach to Fisher's method is Stouffer's Z, based on Z-scores rather than p-values, allowing incorporation of study weights. It is named for the sociologist See more Dependence among statistical tests is generally positive, which means that the p-value of X is too small (anti-conservative) if the dependency is not taken into account. Thus, if … See more Fisher's method is typically applied to a collection of independent test statistics, usually from separate studies having the same null hypothesis. The meta-analysis null hypothesis is that all of the separate null hypotheses are true. The meta-analysis alternative … See more • Extensions of Fisher's method • An alternative source for Fisher's 1948 note: [1] See more
