TX 132 STATISTICAL APPLICATIONS IN TEXTILE ENGINEERING

1. Probability Distribution and Estimations 9
Applications of Binomial, Poisson, Normal, student’s t, chi-square, F distributions in textile manufacturing; point estimates and interval estimations of the parameters of the distribution functions.

2. SIGNIFICANCE TESTS 9
Significance tests – t-test, chi-square test and F test – applicable to textile quality parameters; selection of sample size and significance levels with relevance to textile applications.

3. ANALYSIS OF VARIANCE 8
The objective of analysis of variance; one-way ANOVA; two-way ANOVA; experimental design for ANOVA.

4. DESIGN AND ANALYSIS OF EXPERIMENTS 12
2k full-factorial designs; design and analysis of second-order composite designs – orthogonal and rotatable designs; fitting regression models; calculation of regression coefficients; adequacy test for the regression equations.

5. EXTREME VALUE MODELING 7
Application of Weibull distribution in extreme value modeling for yarn strength; properties of the model; the characteristic smallest value; two-parameter case and three-parameter case; connections with initial distributions.
