### Style

Authors should check an issue of Statistical Science for style. A version of any manuscript that is accepted for publication should be prepared that is entirely double-spaced, including references, with wide margins at sides, top and bottom. (Initial submission need not be double spaced.) Typesetting is facilitated if manuscripts are written using some form of TEX (AMSTEX, LATEX, etc.).

The following formatting will help facilitate the handling of a submission:

- Selected font size should be at least 11 point.
- Interline spacing should be at least 3/16 inch.
- Margins of at least 1.2 inch on all sides should be used.
- Manuscripts should be formatted for 8-1/2 by 11 paper (U.S. letter).

Please see the LaTeX support page for IMS publications to use the IMS recommended template. The typesetter will create the double column format during the production process.

### Title

The title should be descriptive and as concise as is feasible, i.e., it should indicate the topic of the paper as clearly as possible, but every word in it should be pertinent.

### Abbreviated Title

An abbreviated title to be used as a running head is also required. This should normally not exceed 35 characters. For example, an article with the title “The Curvature of a Statistical Model, with Applications to Large-Sample Likelihood Methods,” could have the running head, “Curvature of Statistical Model” or possibly “Asymptotics of Likelihood Methods,” depending on the emphasis to be conveyed.

### Affiliation

Indicate your present institutional affiliation as you would like it to appear.

### Summary

Each manuscript is required to contain a summary, clearly separated from the rest of the paper, which will be printed immediately after the title. Its main purpose is to inform the reader quickly of the nature and results of the paper; it may also be used as an aid in retrieving information. The length of a summary will clearly depend on the length and difficulty of the paper, but in general it should not exceed 150 words. Formulas should be used as sparingly as possible within the summary. The summary should not make reference to results or formulas in the body of the paper-it should be self-contained.

### Title Page Footnotes

Included as a footnote on page 1 should be the headings:

- MSC 2020 subject classifications. Primary-; secondary-
- Key words and phrases

The classification numbers representing the primary and secondary subjects of the article may be found at http://www.ams.org/msc/. The key words and phrases should describe the subject matter of the article; generally they should be taken from the body of the paper.

### Acknowledgment of support

Grants and contracts should also be included in this footnote.

### Figures and Tables

Figures are best prepared as separate postscript or encapsulated postscript files and should be included with the manuscript.

### Formulas

Fractions in the text are preferably written with the solidus or negative exponent; thus, (a + b)/(c + d) is preferred to \frac{a+b}{c+d} and (2\pi)^{-1} or 1/(2 \pi) to \frac{1}{2 \pi}. Also, a^{b(c)} and a_{b(c)} are preferred to a^{b_c} and a_{b_c} , respectively. Complicated exponentials should be represented with the symbol exp. A fractional exponent is preferable to a radical sign.

### References
