Data Analysis

Data Analysis is a iPad App for plotting and analysis of all types of data that can be formulated as x, y pairs. It is particularly useful for quick analysis of various types of scientific data by curve fitting, analysis of data via a standard curve, and analysis of various types of kinetic data including enzyme kinetics.

Data can be entered via the keyboard or imported from the Mail App as a text file (.txt), a comma separated value file (.csv) or a gzipped csv file (.csv.gz). In addition, data can be imported via drag and drop within iTunes. Data files in txt, csv, csv.gz and native formats canalso be imported directly from DropBox.

After data entry the user has the option to average, baseline correct, and/or normalize the data before plotting and fitting.

The user can quickly generate a plot of the data, with axis autoscaling. The user can also customize the graph by varying the size, type and color of the symbols.

The data can be fit to a variety of math equations by non-linear regression including simple functions such as linear, 2nd and 3th order polynomials, as well as power and log functions. Data can also be fit to more complex equations (more being added all the time) for such processes as radioactive decay, enzyme kinetics, 1st and 2nd order chemical reactions, etc.

The fit can then be shown overlaid on the data with different line widths, types and thicknesses.

The results can be emailed in a variety of formats including PDF, PNG and TXT. The graphics in PDF format can be edited with programs like Adobe Illustrator.
