Explore and analyze your datasets. Find patterns within and between variables. Use industry standard statistical techniques without being a stats expert. Get plain english explanations. Data Explorer makes the world of data analysis accessible to the rest of us. Features include:: • Import data files (csv, txt, xls, xlsx) • Enter / edit data by hand • Browse your data set. Apply filters to zero in on the rows that interest you. • Get key stats on each variable and see a graph of its distribution • Variables can be numerical, categorical, or date / time. • Hypothesis tests of means and proportions. One, two, and paired samples. • Two way frequency tables of what values categorical variables take, including phi and Cramer's V statistics • See the distribution of a numerical variables broken down by levels of a categorical variable, including one-way ANOVA, box plot, and density plot • See how two numerical variables vary with each other (correlation) • Explain how one numerical variable varies by a combination of other numerical variables (linear and logistic regression) • Variable transformations. Calculate squares, logs, and other commonly used transformation for use in your regressions and correlations All analysis include: • Results are given in statistical terms and also in plain english • Put as many filters as you want on each analysis to focus in on the part of your data you're interested in Accepts data input in the following formats: • enter data by hand while in the field • import comma separated files (.csv) • import tab delimited text files (.txt) • import excel files (xls and xlsx) • Current version limited to 100,000 rows and 500 columns to be conservative about performance. Export options: • Email PDFs and CSVs of variable summaries and analysis results • Print variable summaries and analysis results • Email CSV of datasets you've entered or edited We are actively developing this app and have additional features lined up. Your feedback can influence the priority we put on different features so please let us know what matters to you!

RPN-34 CE is the first photo-realistic simulation of Hewlett-Packard's popular mid-range scientific calculator HP-34C for the iPhone. Produced from 1979 through 1983, it was the "Basil" member of the third-generation HP calculators known as the "Spice" series. It was the first pocket-calculator ever capable of doing integration and root finding. While the simulator works like the original calculator, a number of carefully designed extensions, along with the tremendously improved speed, make it joy to use even today. RPN-34 CE comes with the programs of HP's "Applications", "Mathematics", "Surveying", "Student Engineering", and "Statistics" application books built-in! Handbooks may be downloaded from CuVee Software's website. Features: • Photo-realistic look-and-feel • Programmable (999 steps), subroutines, 12 labels, 10 flags • 100 registers, "continuous", with full store/recall arithmetic • "Live" register view • Program listing view with intelligent navigation • Program library, easily backed-up via iTunes • Store and retrieve any number of programs • Sharing: e-mail, AirDrop, Dropbox, copy, paste, print • 62 programs pre-installed (53 original HP) Calculator functions: • Integration, root solving • Statistics (mean, standard deviation, linear regression, normal distribution) • Factorial of any number (normal and logarithmic) • Trigonometric and hyperbolic functions (degrees, radians, grads) • Polar/rectangular conversions • Inverse, square root, logarithm, exponential, pi • Storage arithmetic (both store and recall) • Statistics (average, standard deviation, y-estimate, linear regression) • Unit and hours conversions • 31 additional functions not found on the HP-34C, like time and sound Details: cuveesoft.ch/rpn34
