Data: Analysis ToolPak with 13 tools and the Data Analysis dialog (#312)

Browse Source 
data.analysisToolPak runs Descriptive Statistics, Histogram, Correlation,
Covariance, Regression, Moving Average, Exponential Smoothing, Rank and
Percentile, the three t-Tests, F-Test and Anova: Single Factor, writing a
static report to an output range or a new sheet. Non-empty output cells are
refused unless overwrite is set; the dialog asks instead.
