试验数据程序化协方差分析

笔者利用VB6．0编成语言设计了协方差分析计算机程序，用该程序对用玉米秸秆饲喂生长鹅的试验数据进行协方差分析。试验过程是将80只鹅分成5组，在前4组每组分别在常规配合料中加入10％、15％、25％和35％的玉米秸秆粉，观察生长鹅对玉米秸秆的消化利用能力。第5组（处理35％组）除在配合料加入35的玉米秸秆粉外，还加入秸秆分解剂对添加的秸秆进行处理，观察其试验效果（数据见表1）。该程序可以把协方差分析的计算过程、中间数据、计算公式以及各数据、公式之间的关系分步列出，可使数据处理人员，能够全面地了解协方差处理数据的全过程。

The programmized covariance analysis on the experiment data

The computer has been broadly applied. The writer have designed the computer programme on the covariance analysis by the VB6.0 programming language. That programme is used to proceed the coyariance analysis to the the trial data feeding growing geese with corn stalk. The experiment process is that 80 geese are divided into 5 teams, appending 10%,15%,25% and 35% corn stalk powder respectively into normal formulation dietary in each team of the former 4, to observe digestibility of the growing geese to the corn stalk. The pharmaceutical disassembling stalk is appended in the fifth teem to handle corn stalk besides appending 35% corn stalk in formulation dietary （the data is referred in table 1）. The trial result is observed. That programme can list the calculation process, the middle data, the computing formulae, and the relation of data and formulae in the covariance analysis. So it can make the personnel handling data to understand the whole process in the covariance analysis.
