If you have been a user of Fathom version 1.03, you will be interested in features that have been added to the software for version 1.1.
Scroll bars for text objects, test, estimates, and summary tables: When any of these objects are too small to display their entire contents, scroll bars appear giving you the ability to scroll through their contents.
Paste attribute: You can copy an attribute and paste it. The paste is done as an insert before the first selected attribute, or last if there are no selected attributes. If you want to replace an attribute, first delete and then paste. Text copied from other applications (e.g. spreadsheets) can be pasted into a case table as attributes after selecting an attribute in the table.
Select all: The edit menu now contains a Select All command.
Summary tables and tests allow filters: In Version 1.0, you could not add a filter to these objects. Now you can.
Summary table accepts drop of collection name: There are times when you want to compute things about a collection in a summary table, but you are not interested in a particular attribute. Formerly, you had to drop an attribute in the summary table and then delete the attribute. Now you can drag the name of a collection into a summary table and add formulas using attribute names from that collection.
(Windows) or (Mac)-clicking arrows in inspector moves to next selected case: This enables you to browse through selected cases.
Unlimited document size: The size of a Fathom document expands to accommodate the objects you have placed in it.
Sounds preference: The preferences dialog now includes an option to turn off the sounds that Fathom makes.
Graph Info command: When a graph is selected, a command in the Graph menu allows you to display information about the graph. (Formerly the only way to see this information was to double-click on a graph axis.)
Color scatter plots: Drop a continuous attribute into the middle of a scatter plot. The points in the plot will be colored according to the value of that attribute. A color legend appears under the graph.
Plot values on a scatter plot or function plot: A scatter plot or function plot now has a command in the Graph menu, Plot Value, that plots a vertical line for a computed value.
Movable line in function plot: As in a scatter plot, the Graph menu for a function plot allows you to put a movable line in it.
Bar chart bars have heights computed by a formula: In previous versions of Fathom, the height of bars in a bar chart was always the count of the number of cases in the group. Now the bar chart displays a formula from which the height of the bars is computed. The default is "count()" but you can change it to be any computed value; e.g. "mean( height)," or "sum (sales)."
Histograms can have relative frequency scale: When a histogram is plotted, there is a Scale submenu in the Graph menu from which you can choose Count, Density, or Relative Frequency.
New tests:
Test Slope tests the null hypothesis that the slope of the least-squares regression for two attributes is zero.
Test Correlation tests the null hypothesis that the correlation coefficient for two attributes is zero.
New estimates:
Difference of Means computes the confidence interval for the difference between the means of an attribute for two independent samples.
Difference of Proportions computes the confidence interval for the difference of proportions of response for two different groups.
Test for Independence shows expected counts in parentheses next to the actual counts.
Chi-Square Goodness of Fit allows expected probabilities: You can choose to enter your own probabilities. Doing so gives you a table into which you can type the probability for each category.
New organization of statistical functions: The categories are now One Attribute, Two Attributes, and Transformations.
stringToNumber function: This function takes a string (a value that includes letters) as an argument and returns the first number it encounters.
beginsWith function: Takes two arguments and returns true if the first argument as a string begins with the second.
endsWith function: Takes two arguments and returns true if the first argument as a string ends with the second.
stringLength function: Takes a string as an argument and returns the number of characters in the string.
linRegrIntercept: Computes the intercept of the least squares regression line for one independent and one dependent attribute.
linRegrSlope: Computes the slope of the least squares regression line for one independent and one dependent attribute.
rSquared: Computes the square of the correlation coefficient for two continuous attributes.
Q1: Computes the 25th percentile for a continuous attribute; i.e., the first quartile.
Q3: Computes the 75th percentile for a continuous attribute; i.e., the third quartile.
Control pane size in formula editor: The boundary between the formula display area and the keypad can be changed by dragging. Likewise, the size of the help area can be changed by dragging.
Improved sampling behavior: In Version 1.0 many simulations were problematic because sampling copied and evaluated formulas from the source collection. Now formulas are not copied and the source collection is rerandomized only in the special case that there is exactly one case in the source collection.
