# New in 7.0: Data Manipulation

Building on Mathematica's unified symbolic architecture, Mathematica 7 introduces several major new integrated forms of data manipulation—including large-scale support for images, for statistical models, and for geodetic data.

## ReferenceReference

### New in Image Processing & Analysis »

Image create an image from an array of data, and represent any multichannel image

ImageFilter apply an arbitrary filter to an image

Dilation, Erosion, ... — morphological transformations of an image

### New in Statistical Model Analysis »

LinearModelFit construct a linear regression model from data

NonlinearModelFit construct a nonlinear regression model

DesignMatrix construct a design matrix from data

Standardize shift and rescale the data to zero mean and unit variance

Median, Quartiles, QuartileDeviation, ... (modified) — use with symbolic distribution

### New in Interpolation »

BezierFunction create a function representing a Bézier manifold in any dimension

BSplineFunction create a function representing a B-spline manifold in any dimension

Interpolation (modified) — find interpolation at a point

### New Geodesy Functions »

GeoPosition geodetic position specified by latitude, longitude

GeoDistance distance between geodetic positions

GeodesyData, GeoProjectionData reference ellipsoids, datums and projections
