人们研究药物的中心问题是揭示药物的化学结构、理化性质与生物活性之间的内在 联系。19世纪中叶就有人提出了它们的定量关系式: d=F(C)(式2—12) 式中Φ和C分别表示化合物的生物效应和结构性质。后来, Me yer和 Overton的研究表 明,一些化合物的脂水分配系数与麻醉作用呈线性关系 直到20世纪60年代,出现了3个QSAR模型,即 Hansch分析( Hansch analysis)

生物信息学现状和重要研究方向 1.1什么是生物信息学? Genome informatics is a scientific discipline that encompasses all aspects of genome information acquisition, processing, storage, distribution, analysis, and interpretation. 它是一个学科领域,包含着基因组信息的获取、处 理、存储、分配、分析和解释的所有方面

Functional form e We' ve seen that a linear regression can really fit nonlinear relationships 2 Can use logs on RHS, LHS or both Can use quadratic forms ofx's Can use interactions ofx's e How do we know if we've gotten the right functional form for our model? Economics 20- Prof anderson

Dummy variables a dummy variable is a variable that takes on the value l or o Examples: male(= 1 if are male, O otherwise), south(=l if in the south, 0 otherwise), etc dummy variables are also called binar variables. for obvious reasons Economics 20- Prof anderson

Consistency e Under the Gauss-Markov assumptionS OLS IS BLUE, but in other cases it wont always be possible to find unbiased estimators o In those cases, we may settle for estimators that are consistent, meaning as n→>∞,the distribution of the estimator collapses to the parameter value Economics 20- Prof anderson
