一、序言数理统计是医学临床和科研工作中不可缺少的工具.不管是临床病例总结,还是科研实验数据处理,或是普查资料分析,都需要使用数理统计.最早,数理统计的计算工作都是由人来做的.自从有了机械的或电子的计算器之后,基本运算或甚至一些较复杂的运算都可以由机器来做,但是中间结果的抄录和再输入,计算流程的控制都还离不开人的参与.应用电子计算机时,人们只需把所选用的数理统计算法编成程序,连同数据一起输入计算机里,就能很快得到所要的结果.与使用计算器相比,减轻了用户的负担.在需要经常使用数理统计的部门,常把常用的算法编成程序存放在外存贮器里,需要时调入即能使用.由于计算机处理数据的速度很快,因而用户的主要劳动从计算移到数据准备和输入方面.
First, the preface Mathematical statistics is an indispensable tool in medical clinical and scientific research.Whether it is a summary of clinical cases, or scientific experimental data processing, or census data analysis, need to use mathematical statistics.At first, the calculation of mathematical statistics are Done by the human.With the mechanical or electronic calculator, the basic operation or even some more complex operations can be done by the machine, but the intermediate results of transcription and re-input, the control of the calculation process are still Unobtrusive Participation When using a computer, people simply compile the chosen mathematical statistics algorithm into a program and enter it along with the data in the computer to get the desired results very quickly. Compared with the use of calculators, The user’s burden.In the need to often use mathematical statistics departments, often the commonly used algorithm compiled into the program stored in external memory, when necessary, can be transferred to use.As the computer processing data quickly, so the user’s main labor Move from calculation to data preparation and input.
