First Look into the Data
February 22, 2008
This is the raw data of settling column with alum dose of 15mg/L and turbidity vs. terminal velocity plot.
Polynomial Regression is evaluated on turbidity vs. terminal velocity plot, where n = number of polynomial degree. (a) n=1, (b) n=2, (c) n=3 and (d) n=4
However for n>4, the trendlines look almost similar. The next step is to evaluate statistical analysis.
